rustdoc: update to pulldown-cmark 0.11
r? rustdoc
This pull request updates rustdoc to the latest version of pulldown-cmark. Along with adding new markdown extensions (which this PR doesn't enable), the new pulldown-cmark version also fixes a large number of bugs. Because all text files successfully parse as markdown, these bugfixes change the output, which can break people's existing docs.
A crater run, https://github.com/rust-lang/rust/pull/121659, has already been run for this change.
The first commit upgrades and fixes rustdoc. The second commit adds a lint for the footnote and block quote parser changes, which break the largest numbers of docs in the Crater run. The strikethrough change was mitigated in pulldown-cmark itself.

Make mtime of reproducible tarballs dependent on git commit
Since https://github.com/rust-lang/rust/pull/123246, our tarballs should be fully reproducible. That means that the mtime of all files and directories in the tarballs is set to the date of the first Rust commit (from 2006). However, this is causing some mtime invalidation issues (https://github.com/rust-lang/rust/issues/125578#issuecomment-2141068906).
Ideally, we would like to keep the mtime reproducible, but still update it with new versions of Rust. That's what this PR does. It modifies the tarball installer bootstrap invocation so that if the current rustc directory is managed by git, we will set the UTC timestamp of the latest commit as the mtime for all files in the archive. This means that the archive should be still fully reproducible from a given commit SHA, but it will also be changed with new beta bumps and `download-rustc` versions.
Note that only files are set to this mtime, directories are still set to the year 2006, because the `tar` library used by `rust-installer` doesn't allow us to selectively override mtime for directories (or at least I haven't found it). We could work around that by doing all the mtime modifications in bootstrap, but that would require more changes. I think/hope that just modifying the file mtimes should be enough. It should at least fix cargo `rustc` mtime invalidation.

Re-implement a type-size based limit
r? lcnr
This PR reintroduces the type length limit added in #37789, which was accidentally made practically useless by the caching changes to `Ty::walk` in #72412, which caused the `walk` function to no longer walk over identical elements.
Hitting this length limit is not fatal unless we are in codegen -- so it shouldn't affect passes like the mir inliner which creates potentially very large types (which we observed, for example, when the new trait solver compiles `itertools` in `--release` mode).
This also increases the type length limit from `1048576 == 2 ** 20` to `2 ** 24`, which covers all of the code that can be reached with craterbot-check. Individual crates can increase the length limit further if desired.
Perf regression is mild and I think we should accept it -- reinstating this limit is important for the new trait solver and to make sure we don't accidentally hit more type-size related regressions in the future.

Give remote-test-client a longer timeout
In https://github.com/rust-lang/rust/pull/126959, ``@Mark-Simulacrum`` suggested we simply extend the timeout of the `remote-test-client` instead of making it configurable. This is acceptable for my use case.
I'm doing some work with a remote host running tests using `x.py`'s remote test runner system.
After building the `remote-test-server` with:
```bash
./x build src/tools/remote-test-server --target aarch64-unknown-linux-gnu
```
I can transfer the `remote-test-server` to the remote and set up a port forwarded SSH connection, then I run:
```bash
TEST_DEVICE_ADDR=127.0.0.1:12345 ./x.py test library/core --target aarch64-unknown-linux-gnu
```
This works great if the host is nearby, however if the average round trip time is over 100ms (the timeout), it creates problems as it silently trips the timeout.
This PR extends that timeout to a less strict 2s.

Bootstrap: Try renaming the file if removing fails
Second attempt at working around https://github.com/rust-lang/rust/issues/127126
If we can't remove the file, then try renaming it. This will leave the destination path free to use.

Fix `FnMut::call_mut`/`Fn::call` shim for async closures that capture references
I adjusted async closures to be able to implement `Fn` and `FnMut` *even if* they capture references, as long as those references did not need to borrow data from the closure captures themselves. See #125259.
However, when I did this, I didn't actually relax an assertion in the `build_construct_coroutine_by_move_shim` shim code, which builds the `Fn`/`FnMut`/`FnOnce` implementations for async closures. Therefore, if we actually tried to *call* `FnMut`/`Fn` on async closures, it would ICE.
This PR adjusts this assertion to ensure that we only capture immutable references in closures if they implement `Fn`/`FnMut`. It also adds a bunch of tests and makes more of the async-closure tests into `build-pass` since we often care about these tests actually generating the right closure shims and stuff. I think it might be excessive to *always* use build-pass here, but 🤷 it's not that big of a deal.

The CDN has been down for a few hours. Switch to an alternative for the
time being so we can unblock CI.
It appears that the CDN is quite a bit faster, so we will likely want to
switch back when available.
improve the way bootstrap handles rustlib components
When CI rustc is enabled, bootstrap tries to symlink the rust source (project root) into target sysroot right before copying it from the CI rustc's sysroot. This becomes a problem in CI builders (which we currently don't see because they don't use CI rustc) because the copying part will fail as [they run on read-only mode](ef3d6fd700/src/ci/docker/run.sh (L233)).
This change fixes the problem by copying `rustc-src` from the CI rustc sysroot and only symlinking `rustc-src` from the rust source when download-rustc is not enabled.

Fix x86_64 code being produced for bare-metal LoongArch targets' `compiler_builtins`
Formerly the `loongarch*-*-none*` targets were added to the `dist-various-2` CI job, but no corresponding toolchain was added along with them. This meant the `compiler_builtins` for the targets were built with the host toolchain.
As the other `dist-various` toolchains are mostly pre-built so far, to avoid burdening them with crosstool-ng builds, simply move the two bare-metal LoongArch targets to the `dist-loongarch64-linux` job which has a ready-to-use LoongArch toolchain. With the proper CFLAGS applied it is possible to build artifacts suitable for bare-metal. I verified that the `compiler_builtins` objects are now correctly produced regarding architecture and ABI, with the changes here applied.
Fixes#125908.

Cleanup bootstrap check-cfg
This PR cleanup many custom `check-cfg` in bootstrap that have been accumulated over the years.
As well as updating some outdated comments.
