Move `std_detect` into stdlib
This PR moves the `std_detect` crate from `stdarch` to be a part of rust-lang/rust instead.
The first commit actually moves the whole directory from the stdarch Josh subtree, so that git blame history is kept intact. Then I had to make a few changes to appease `tidy`.
The most complex thing here is porting the tests. We can't have `std_detect` both in r-l/r and stdarch, because they could get desynchronized, so we have to perform the move more or less "atomically", which means that we also have to port all the existing `std_detect` tests from the `stdarch` repository.
The stdarch repo runs the following `std_detect` tests:
### Build
The `build-std-detect.sh` script (https://github.com/rust-lang/stdarch/blob/e2b6512aed87df45294ae680181eeef7a802cd95/ci/build-std-detect.sh) builds `std_detect` using the nightly compiler for several targets. This will be subsumed by normal `x build library` on our Tier 1/2 targets. However, the stdarch repository also tests the following targets:
- aarch64-unknown-freebsd
- armv6-unknown-freebsd
- powerpc-unknown-freebsd
- powerpc64-unknown-freebsd
- aarch64-unknown-openbsd
Which we don't build/test on our CI currently. I think we have mostly two options here:
1) Ignore these targets
2) Create a special CI job that will build stage 1 rustc and then cross-compile std (or just the `std_detect` crate?) for these targets.
### Documentation
The `dox.sh` script (https://github.com/rust-lang/stdarch/blob/3fec5adcd52a815f227805d4959a25b6402c7fd5/ci/dox.sh) builds and documents `std_detect` for several targets. All of them are Tier 2/we have `dist-` jobs for them, so I think that we can just skip this and let our normal CI subsume it?
### Tests
The `run.sh` script (https://github.com/rust-lang/stdarch/blob/1b201cec2cca7465602a65ed6ae60517224b15f3/ci/run.sh) runs `cargo test` on `std_detect` with a bunch of variations of feature flags. This will be subsumed by `x test library` in our CI. The only problem is that `stdarch` runs these tests for a ludicrous number of targets:
```
- tuple: i686-unknown-linux-gnu
- tuple: x86_64-unknown-linux-gnu

```
We definitely do not run *tests* for all of these targets on our CI.
# Outcome
We have decided to just subsume std_detect tests by our normal test suite for now, and not create a separate CI job. Therefore, this PR performs the following changes in target testing for `std_detect`:
The following T3 targets would go from "build" to "nothing":
```
aarch64-unknown-freebsd (T3)
armv6-unknown-freebsd (T3)
powerpc-unknown-freebsd (T3)
powerpc64-unknown-freebsd (T3)
aarch64-unknown-openbsd (T3)
```
The following T3 targets would go from "test" to "nothing":
```
aarch64_be-unknown-linux-gnu (T3)
riscv32gc-unknown-liux-gnu (T3)
```
The following T2 targets would go from "test" to "build":
```
arm-unknown-linux-gnueabihf (T2)
armv7-unknown-linux-gnueabihf (T2)
riscv64gc-unknown-linux-gnu (T2)
powerpc-unknown-linux-gnu (T2)
powerpc64-unknown-linux-gnu (T2)
powerpc64le-unknown-linux-gnu (T2)
s390x-unknown-linux-gnu (T2)
i586-unknown-linux-gnu (T2)
loongarch64-unknown-linux-gnu (T2)
wasm32-wasip1 (T2)
x86_64-apple-ios-macabi (T2)
aarch64-apple-ios-macabi (T2)
aarch64-pc-windows-msvc (T2)
armv7-unknown-linux-gnueabihf (T2)
loongarch64-unknown-linux-gnu (T2)
powerpc-unknown-linux-gnu (T2)
```
I have confirmed in https://github.com/rust-lang/stdarch/pull/1873 that the current version of this PR would pass stdarch's CI testsuite.

And add `&self` lifetime support
Example
===
Rename to `this`
```rust
struct Foo<T>(T);
impl Foo<i32> {
fn foo(&'static self$0) {}
}
```
Old:
```rust
struct Foo<T>(T);
impl Foo<i32> {
fn foo(this: &Foo) {}
}
```
Fixes:
```rust
struct Foo<T>(T);
impl Foo<i32> {
fn foo(this: &'static Self) {}
}
```

Rename `tests/{assembly,codegen}` into `tests/{assembly,codegen}-llvm` and ignore these testsuites if configured backend doesn't match
Follow-up of https://github.com/rust-lang/rust/pull/144125.
This PR changes `compiletest` so that `asm` tests are only run if they match the current codegen backend. To better reflect it, I renamed the `tests/ui/asm` folder into `tests/ui/asm-llvm`. Like that, we can add new asm tests for other backends if we want without needing to add extra code to `compiletest`.
Next step will be to use the new code annotations added in rust-lang/rust#144125 to ignore ui tests failing in cg_gcc until it's fixed on our side.

Fix empty target_config in apply_rust_config bootstrap

tidy: move rustdoc js stuff into a tidy extra check
Most of these were factored out of CI scripts, but `eslint` in particular was previously implemented with its own special cased logic.
A new option has been added to bootstrap, `build.tidy-extra-checks`, which serves as a default value for the `--extra-checks` flag. This is mostly for the benefit of rustdoc js maintainers, but should also help bootstrap py maintainers.
Additionally, `--extra-checks=cpp` has been documented.
I'm not super happy with how long the extra check names are in comparison to the others (in particular `typecheck`), but I couldn't think of anything better (I didn't want to name it `tsc` on the off chance we want to switch to a different typechecking engine in the future).
It would be nice to convert the extra checks arg into a proper enum, both for warning on unknown values and to provide better shell completion.

The previous manual parsing of `serde_json::Value` was a lot of
complicated code and extremely error-prone. It was full of janky
behavior like sometimes ignoring type errors, sometimes erroring for
type errors, sometimes warning for type errors, and sometimes just
ICEing for type errors (the icing on the top).
Additionally, many of the error messages about allowed values were out
of date because they were in a completely different place than the
FromStr impls. Overall, the system caused confusion for users.
I also found the old deserialization code annoying to read. Whenever a
`key!` invocation was found, one had to first look for the right macro
arm, and no go to definition could help.
This PR replaces all this manual parsing with a 2-step process involving
serde.
First, the string is parsed into a `TargetSpecJson` struct. This struct
is a 1:1 representation of the spec JSON. It already parses all the
enums and is very simple to read and write.
Then, the fields from this struct are copied into the actual `Target`.
The reason for this two-step process instead of just serializing into a
`Target` is because of a few reasons
1. There are a few transformations performed between the two formats
2. The default logic is implemented this way. Otherwise all the default
field values would have to be spelled out again, which is
suboptimal. With this logic, they fall out naturally, because
everything in the json struct is an `Option`.
Overall, the mapping is pretty simple, with the vast majority of fields
just doing a 1:1 mapping that is captured by two macros. I have
deliberately avoided making the macros generic to keep them simple.
All the `FromStr` impls now have the error message right inside them,
which increases the chance of it being up to date. Some "`from_str`"
impls were turned into proper `FromStr` impls to support this.
The new code is much less involved, delegating all the JSON parsing
logic to serde, without any manual type matching.
This change introduces a few breaking changes for consumers. While it is
possible to use this format on stable, it is very much subject to
change, so breaking changes are expected. The hope is also that because
of the way stricter behavior, breaking changes are easier to deal with,
as they come with clearer error messages.
1. Invalid types now always error, everywhere. Previously, they would
sometimes error, and sometimes just be ignored (which meant the users
JSON was still broken, just silently!)
2. This now makes use of `deny_unknown_fields` instead of just warning
on unused fields, which was done previously. Serde doesn't make it
easy to get such warning behavior, which was the primary reason that
this now changed. But I think error behavior is very reasonable too.
If someone has random stale fields in their JSON, it is likely
because these fields did something at some point but no longer do,
and the user likely wants to be informed of this so they can figure
out what to do.
This is also relevant for the future. If we remove a field but
someone has it set, it probably makes sense for them to take a look
whether they need this and should look for alternatives, or whether
they can just delete it. Overall, the JSON is made more explicit.
This is the only expected breakage, but there could also be small
breakage from small mistakes. All targets roundtrip though, so it can't
be anything too major.
