Liberate `aarch64-gnu-debug` from the shackles of `--test-args=clang`
### Changes
- Drop `--test-args=clang` from `aarch64-gnu-debug` so run-make tests that are `//@ needs-force-clang-based-tests` no longer only run if their test name contains `clang` (which is a very cool footgun).
- Reorganize run-make-suport library slightly to accommodate a raw gcc invocation.
- Fix `tests/run-make/mte-ffi/rmake.rs` to use `gcc` instead of *a* c compiler.

ci: Enable full `debuginfo-level=2` in `DEPLOY_ALT`
It will be slower to build and produce larger artifacts, but hopefully
it will help catch debuginfo regressions sooner, especially for problems
that LLVM assertions would uncover.

Delete the `cfg(not(parallel))` serial compiler
Since it's inception a long time ago, the parallel compiler and its cfgs have been a maintenance burden. This was a necessary evil the allow iteration while not degrading performance because of synchronization overhead.
But this time is over. Thanks to the amazing work by the parallel working group (and the dyn sync crimes), the parallel compiler has now been fast enough to be shipped by default in nightly for quite a while now.
Stable and beta have still been on the serial compiler, because they can't use `-Zthreads` anyways.
But this is quite suboptimal:
- the maintenance burden still sucks
- we're not testing the serial compiler in nightly
Because of these reasons, it's time to end it. The serial compiler has served us well in the years since it was split from the parallel one, but it's over now.
Let the knight slay one head of the two-headed dragon!
#113349
Note that the default is still 1 thread, as more than 1 thread is still fairly broken.

This commit is the final step in the journey of renaming the historical
`wasm32-wasi` target in the Rust compiler to `wasm32-wasip1`. Various
steps in this journey so far have been:
* 2023-04-03: rust-lang/compiler-team#607 - initial proposal for this rename
* 2024-11-27: rust-lang/compiler-team#695 - amended schedule/procedure for rename
* 2024-01-29: rust-lang/rust#120468 - initial introduction of `wasm32-wasip1`
* 2024-06-18: rust-lang/rust#126662 - warn on usage of `wasm32-wasi`
* 2024-11-08: this PR - remove the `wasm32-wasi` target
The full transition schedule is in [this comment][comment] and is
summarized with:
* 2024-05-02: Rust 1.78 released with `wasm32-wasip1` target
* 2024-09-05: Rust 1.81 released warning on usage of `wasm32-wasi`
* 2025-01-09: Rust 1.84 to be released without the `wasm32-wasi` target
This means that support on stable for the replacement target of
`wasm32-wasip1` has currently been available for 6 months. Users have
already seen warnings on stable for 2 months about usage of
`wasm32-wasi` and stable users have another 2 months of warnings before
the target is removed from stable.
This commit is intended to be the final step in this transition so the
source tree should no longer mention `wasm32-wasi` except in historical
reference to the older name of the `wasm32-wasip1` target.

Run the full stage 2 `run-make` test suite in `x86_64-gnu-debug`
Run the full `run-make` test suite in the `x86_64-gnu-debug` CI job. This is currently the *only* CI job where `//@ needs-force-clang-based-test` will be satisfied, so some `run-make` tests will literally never be run otherwise. Before this PR, the CI job only ran `run-make` tests which contains the substring `clang` in its test name, which is both (1) a footgun because it's very easy to forget and (2) it masks tests that would otherwise fail (even failing to compile) because the test is skipped if doesn't have a `clang` in its test name.
With the environment of `x86_64-gnu-debug`, two `run-make` tests failed before this PR:
1. `tests/run-make/issue-84395-lto-embed-bitcode/rmake.rs`: this was broken for a long time because `objcopy` in llvm bin tools was renamed to `llvm-objcopy`. This test was converted into a rmake.rs test, rather straight forward.
2. `tests/run-make/cross-lang-lto-riscv-abi/rmake.rs`: this was broken for a long time and never worked. The old version inspected human-readable output of `llvm-readobj --file-header` looking for substring `EF_RISCV_FLOAT_ABI_DOUBLE`, but the human-readable output will only contain something like `Flags: 0x5, RVC, double-float ABI`, hence it will never match. This test was fixed by instead using the `object` crate to actually decode the ELF headers looking for the specific `e_flags` based on reading the RISCV ELF psABI docs.
This PR is best reviewed commit-by-commit, two commits setup the support library for functionality and two commits are for each of the failing `run-make` tests.
I had to bump the `x86_64-gnu-debug` job to be ran with a runner with larger disk space.
Part of #132034.

(ci) Update macOS Xcode to 15
This updates the macOS builders to Xcode 15. The aarch64 images will be removing Xcode 14 and 16 very soon (https://github.com/actions/runner-images/issues/10703), so we will need to make the switch to continue operating. The linked issue also documents GitHub's new policy for how they will be updating Xcode in the future. Also worth being aware of is the future plans for x86 runners documented in https://github.com/actions/runner-images/issues/9255 and https://github.com/actions/runner-images/issues/10686, which will impact our future upgrade behaviors.
I decided to also update the Xcode in the x86_64 runners, even though they are not being removed. It felt better to me to have all macOS runners on the same (major) version of Xcode. However, note that the x86_64 runners do not have the latest version of 15 (15.4), so I left them at 15.2 (which is currently the default Xcode of the runner).
Xcode 15 was previously causing problems (see #121058) which seem to be resolved now. `@bjorn3` fixed the `invalid r_symbolnum` issue with cranelift. The issue with clang failing to link seems to be fixed, possibly by the update of the pre-built LLVM from 14 to llvm 15 in https://github.com/rust-lang/rust/pull/124850, or an update in our source version of LLVM. I have run some try builds and at least LLVM seems to build (I did not run any tests).
Closes#121058
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.
