Rustdoc ty consistency fixes
Changes to make rustdoc cleaning of ty more consistent with hir, and hopefully use it in more places.

Only create a single expansion for each inline integration.
The inlining integrator used to create one expansion for each span from the callee body.
This PR reverses the logic to create a single expansion for the whole call,
which is more consistent with how macro expansions work for macros.
This should remove the large memory regression in #91743.

Fix duplicated impl links
Fixes #78701.
The problem is that the blanket impl has the same ID as the other impl, except that we don't derive IDs when we generate the sidebar. We now do.

Wire up unstable rustc --check-cfg to rustdoc
This pull-request wire up the new unstable `--check-cfg` option from `rustc` to `rustdoc` as [requested](https://github.com/rust-lang/rust/pull/93915#discussion_r807560445) in the [pull-request](https://github.com/rust-lang/rust/pull/93915) that introduce `--check-cfg`.
The motivation was describe in the original PR by ``@jyn514`` who wrote https://github.com/rust-lang/rust/pull/89346#issuecomment-930129761:
> > add plumbing to pass --check-cfg from rustdoc (do we want this one?)
>
> It would be useful, I think, it catches issues like cfg(doctst) or something (and in general I would like expansion to match rustc as closely as possible).

Bump bootstrap to 1.60
This bumps the bootstrap compiler to 1.60 and cleans up cfgs and Span's rustc_pass_by_value (enabled by the bootstrap bump).

Remove in band lifetimes
As discussed in t-lang backlog bonanza, the `in_band_lifetimes` FCP closed in favor for the feature not being stabilized. This PR removes `#![feature(in_band_lifetimes)]` in its entirety.
Let me know if this PR is too hasty, and if we should instead do something intermediate for deprecate the feature first.
r? `@scottmcm` (or feel free to reassign, just saw your last comment on #44524)
Closes #44524

Provide ignore message in the result of test
Provide ignore the message in the result of the test.
This PR does not need RFC, because it is about the presentation of the report of `cargo test`.
However, the following document listed here helps you to know about PR.
- [RFC](https://github.com/rust-lang/rfcs/pull/3217)

rustc_errors: let `DiagnosticBuilder::emit` return a "guarantee of emission".
That is, `DiagnosticBuilder` is now generic over the return type of `.emit()`, so we'll now have:
* `DiagnosticBuilder<ErrorReported>` for error (incl. fatal/bug) diagnostics
* can only be created via a `const L: Level`-generic constructor, that limits allowed variants via a `where` clause, so not even `rustc_errors` can accidentally bypass this limitation
* asserts `diagnostic.is_error()` on emission, just in case the construction restriction was bypassed (e.g. by replacing the whole `Diagnostic` inside `DiagnosticBuilder`)
* `.emit()` returns `ErrorReported`, as a "proof" token that `.emit()` was called
(though note that this isn't a real guarantee until after completing the work on
#69426)
* `DiagnosticBuilder<()>` for everything else (warnings, notes, etc.)
* can also be obtained from other `DiagnosticBuilder`s by calling `.forget_guarantee()`
This PR is a companion to other ongoing work, namely:
* #69426
and it's ongoing implementation:
#93222
the API changes in this PR are needed to get statically-checked "only errors produce `ErrorReported` from `.emit()`", but doesn't itself provide any really strong guarantees without those other `ErrorReported` changes
* #93244
would make the choices of API changes (esp. naming) in this PR fit better overall
In order to be able to let `.emit()` return anything trustable, several changes had to be made:
* `Diagnostic`'s `level` field is now private to `rustc_errors`, to disallow arbitrary "downgrade"s from "some kind of error" to "warning" (or anything else that doesn't cause compilation to fail)
* it's still possible to replace the whole `Diagnostic` inside the `DiagnosticBuilder`, sadly, that's harder to fix, but it's unlikely enough that we can paper over it with asserts on `.emit()`
* `.cancel()` now consumes `DiagnosticBuilder`, preventing `.emit()` calls on a cancelled diagnostic
* it's also now done internally, through `DiagnosticBuilder`-private state, instead of having a `Level::Cancelled` variant that can be read (or worse, written) by the user
* this removes a hazard of calling `.cancel()` on an error then continuing to attach details to it, and even expect to be able to `.emit()` it
* warnings were switched to *only* `can_emit_warnings` on emission (instead of pre-cancelling early)
* `struct_dummy` was removed (as it relied on a pre-`Cancelled` `Diagnostic`)
* since `.emit()` doesn't consume the `DiagnosticBuilder` <sub>(I tried and gave up, it's much more work than this PR)</sub>,
we have to make `.emit()` idempotent wrt the guarantees it returns
* thankfully, `err.emit(); err.emit();` can return `ErrorReported` both times, as the second `.emit()` call has no side-effects *only* because the first one did do the appropriate emission
* `&mut Diagnostic` is now used in a lot of function signatures, which used to take `&mut DiagnosticBuilder` (in the interest of not having to make those functions generic)
* the APIs were already mostly identical, allowing for low-effort porting to this new setup
* only some of the suggestion methods needed some rework, to have the extra `DiagnosticBuilder` functionality on the `Diagnostic` methods themselves (that change is also present in #93259)
* `.emit()`/`.cancel()` aren't available, but IMO calling them from an "error decorator/annotator" function isn't a good practice, and can lead to strange behavior (from the caller's perspective)
* `.downgrade_to_delayed_bug()` was added, letting you convert any `.is_error()` diagnostic into a `delay_span_bug` one (which works because in both cases the guarantees available are the same)
This PR should ideally be reviewed commit-by-commit, since there is a lot of fallout in each.

As an example:
#[test]
#[ignore = "not yet implemented"]
fn test_ignored() {
...
}
Will now render as:
running 2 tests
test tests::test_ignored ... ignored, not yet implemented
test result: ok. 1 passed; 0 failed; 1 ignored; 0 measured; 0 filtered out; finished in 0.00s

Previously it always returned `MacroKind::Bang` while some of those macros are actually attributes and derives

Fix rustdoc infinite redirection generation
Someone came to me about a funny bug they had when clicking on any link on [this page](https://world.pages.gitlab.gnome.org/Rust/libadwaita-rs/stable/latest/docs/libadwaita/builders/index.html): it ended one page redirecting to itself indefinitely.
I was able to make a minimum reproducible case to trigger this bug which I now use as a test.

rustdoc: resolve intra-doc links when checking HTML
Similar to #86451
CC #67799
Given this test case:
```rust
#![warn(rustdoc::invalid_html_tags)]
#![warn(rustdoc::broken_intra_doc_links)]
pub struct ExistentStruct<T>(T);
/// This [test][ExistentStruct<i32>] thing!
pub struct NoError;
```
This pull request silences the following, spurious warning:
```text

rustdoc-json: buffer output
It turns out we were doing syscalls for each part of the json syntax
Before:
```
...
[pid 1801267] write(5, "\"", 1) = 1
[pid 1801267] write(5, ",", 1) = 1
[pid 1801267] write(5, "\"", 1) = 1
...
```
After:
```
[pid 1974821] write(5, "{\"root\":\"0:0\",\"crate_version\":nu"..., 1575) = 1575
```
In one benchmark (one struct, almost all time in `std`), this gives ~2x perf

Implement --check-cfg option (RFC 3013), take 2
This pull-request implement RFC 3013: Checking conditional compilation at compile time (https://github.com/rust-lang/rfcs/pull/3013) and is based on the previous attempt https://github.com/rust-lang/rust/pull/89346 by `@mwkmwkmwk` that was closed due to inactivity.
I have address all the review comments from the previous attempt and added some more tests.

Pass `--test` flag through rustdoc to rustc so `#[test]` functions can be scraped
As a part of stabilizing the scrape examples extension in Cargo, I uncovered a bug where examples cannot be scraped from tests. See this test: https://github.com/rust-lang/cargo/pull/10343/files#diff-27aa4f012ebfebaaee61498d91d2370de460628405d136b05e77efe61e044679R2496
The issue is that when rustdoc is run on a test file, because `--test` is not passed as a rustc option, then functions annotated with `#[test]` are ignored by the compiler. So this PR changes rustdoc so when `--test` is passed in conjunction with a `--scrape-example-<suffix>` flag, then the `test` field of `rustc_interface::Config` is true.

rustdoc: Collect traits in scope for lang items
Inherent impls on primitive types are not included in the list of all inherent impls in the crate (`inherent_impls_in_crate_untracked`), they are taken from the list of lang items instead, but such impls can also be inlined by rustdoc, e.g. if something derefs to a primitive type.
