Removing this heuristic doesn't show up as a regression in perf run

Allow `#![doc(test(attr(..)))]` everywhere
This PR adds the ability to specify [`#![doc(test(attr(..)))]`](https://doc.rust-lang.org/nightly/rustdoc/write-documentation/the-doc-attribute.html#testattr) ~~at module level~~ everywhere in addition to allowing it at crate-root.
This is motivated by a recent PR #140323 (by ````@tgross35)```` where we have to duplicate 2 attributes to every single `f16` and `f128` doctests, by allowing `#![doc(test(attr(..)))]` at module level (and everywhere else) we can omit them entirely and just have (in both module):
```rust
#![doc(test(attr(feature(cfg_target_has_reliable_f16_f128))))]
#![doc(test(attr(expect(internal_features))))]
```
Those new attributes are appended to the one found at crate-root or at a previous module. Those "global" attributes are compatible with merged doctests (they already were before).
Given the small addition that this is, I'm proposing to insta-stabilize it, but I can feature-gate it if preferred.

rustdoc: cleanups relating to allocations
These commits generally clean up the code a bit and also reduce allocation rates a bit.

Stabilize flags for doctest cross compilation
This makes the following changes in preparation for supporting doctest cross-compiling in cargo:
- Renames `--runtool` and `--runtool-arg` to `--test-runtool` and `--test-runtool-arg` to maintain consistency with other `--test-*` arguments.
- Stabilizes the `--test-runtool` and `--test-runtool-arg`. These are needed in order to support cargo's `target.runner` option which specifies a runner to execute a cross-compiled doctest (for example, qemu).
- Stabilizes the `--enable-per-target-ignores` flag by removing it and making it unconditionally enabled. This makes it possible to disable a doctest on a per-target basis, which I think will be helpful for rolling out this feature.
These changes were suggested in https://rust-lang.zulipchat.com/#narrow/channel/266220-t-rustdoc/topic/stabilizing.20doctest.20xcompile/near/409281127
The intent is to stabilize the doctest-xcompile feature in cargo. This will help ensure that for projects that do cross-compile testing that their doctests are also covered. Currently there is a somewhat surprising behavior that they are ignored.

We should enable these to avoid misinterpreting uses of the extended
syntax as code blocks. This happens in practice with multi-paragraph
footnotes, as discovered in #139064.

rustc_resolve: fix instability in lib.rmeta contents
rust-lang/rust@23032f31c91f2 accidentally introduced some nondeterminism in the ordering of lib.rmeta files, which we caught in our bazel-based builds only recently due to being further behind than normal. In my testing, this fixes the issue.

This removes the `--enable-per-target-ignores` and enables it
unconditionally.

`librustdoc`: clippy fixes
First commit is all machine-generated fixes,
next two are some more lints fixed by hand/misc. cleanups
Inspired by the redundant `.and_then()` added in https://github.com/rust-lang/rust/pull/137320 , and [this comment](https://github.com/rust-lang/rust/pull/138090#discussion_r1983111856)

This commit takes advantage of a feature in pulldown-cmark that
makes the list of link definitions available to the consuming
application. It produces unresolved link warnings for refdefs
that aren't used, and can now produce exact spans for the dest
even when it has escapes.

Correctly escape hashtags when running `invalid_rust_codeblocks` lint
Fixes #136899.
We forgot to use `map_line` when we wrote this lint.

[rustdoc] Remove intra-doc links dead code
While working on https://github.com/rust-lang/rust/pull/130278, I wondered what `resolve_display_text` was doing. I removed it and ran all rustdoc tests, and nothing failed. Are some intra-doc links tests missing or is it really dead code? Couldn't figure it out.
