Bump Fuchsia toolchain for testing
This updates the Fuchsia SDK used to test rust on Fuchsia to 26.20241211.7.1, and clang to the development version 20 from 388d7f144880dcd85ff31f06793304405a9f44b6.
```@steven807``` asked me to take over the PR. Since I don't have commit access to his repo, I just cherry picked his patch here.

CI: rfl: move job forward to Linux v6.13-rc1
Linux v6.13-rc1 contains commit 28e848386b92 ("rust: block: fix formatting of `kernel::block::mq::request` module"), which in turn contains commit c95bbb59a9b2 ("rust: enable arbitrary_self_types and remove `Receiver`"), which is why we had a hash rather than a tag.

ci update freebsd version proposal, freebsd 12 being eol
raising to the lowest still active supported freebsd version.
From 13.1 (already eol too), freebsd introduces a cpu affinity layer
with linux. It also introduces a api compatible copy_file_range which
can be used like its linux's counterpart.
The former is essential to build https://github.com/rust-lang/rust/pull/120589, therefore breaks the backward
compatibility with the previous FreeBSD releases.
Blocked on https://github.com/rust-lang/rust/issues/130465
[A recent commit in LLVM](ab930ee7ca) modified the JSON output of LLVM. The LLVM change renamed "Notes" to "NoteSections" and inserted a new "Notes" key nested under each "NoteSection".
This change shores up exceptions around reading the JSON output of llvm-readelf and reads from "NoteSections" instead of the non-existent "Notes".

This particular target does not expand into much code, so it is a good
first candidate to see if we could keep this in the CI.

This change will also remove the current warnings in the build due to
`rustfmt` not being available (for `bindgen` output):
error: 'rustfmt' is not installed for the custom toolchain 'local'.
note: this is a custom toolchain, which cannot use `rustup component add`
help: if you built this toolchain from source, and used `rustup toolchain link`, then you may be able to build the component with `x.py`
Failed to run rustfmt: Internal rustfmt error (non-fatal, continuing)

Apparently tools like `rustfmt` require it in order to find the right
`librustc_driver.so` without extra tweaks.

More work on `zstd` compression
r? ``@Kobzol`` as we've discussed this.
This is a draft to show the current approach of supporting zstd in compiletest, and making the tests using it unconditional.
Knowing whether llvm/lld was built with `LLVM_ENABLE_ZSTD` is quite hard, so there are two strategies. There are details in the code, and we can discuss this approach. Until we know the config used to build CI artifacts, it seems our options are somewhat limited in any case.
zlib compression seems always enabled, so we only check this in its dedicated test, allowing the test to ignore errors due to zstd not being supported.
The zstd test is made unconditional in what it tests, by relying on `needs-llvm-zstd` to be ignored when `llvm.libzstd` isn't enabled in `config.toml`.

Update `crosstool-ng` for loongarch64
The current cross-compilation toolchain for the LoongArch64 target consists of GCC 13.2.0, Binutils 2.40, and Glibc 2.36. However, Binutils 2.40 has known issues that in broken binaries without any error reports:
- https://github.com/rust-lang/rust/issues/121289
- https://github.com/cross-rs/cross/issues/1538
This patch upgrades the cross-compilation toolchain for the LoongArch64 target to resolve these issues.
- GCC: 13.2.0 -> 14.2.0
- Binutils: 2.40 -> 2.42
The new binaries remain compatible with the existing GCC 13.2.0/Glibc 2.36 distribution, and no issues have been identified.

The default repository server setting has changed on Fuchsia (default is
newly "false"). Now, in order to start the repository server, the config
`repository.server.enabled` must be set to true.
Since the `rfl` CI job has not had almost any issue for some weeks,
it is a good time to try to increase a bit the scope of what it tests.
The kernel does not use any particular `rustdoc` unstable issue (apart
from the doctests ones) so far, so in principle it should not introduce
extra issues here, and may be a good extra test case for Rust.
In addition, it may help to test new unstable features in the future.
In the worst case, we can revert it.

We were already generating the doctests, which should already catch most
issues with our hack around `--test-builder` and `--no-run`.
However, we were not building the result of that transformation, thus
build it for completeness and to ensure the hack may not have produced
something completely broken.
In the worst case, we can revert it.

The tag has been released today, and since the original hash we had in
the Rust CI (which was ~v6.10-rc1), we have accumulated a fair amount
of changes and new code.
In particular, v6.11-rc1 is the first Linux tag where the kernel is
supporting an actual minimum Rust version (1.78.0), rather than a
single version.
