Migrate `reproducible-build-2` and `stable-symbol-names` `run-make` tests to rmake

Use `object` in `run-make/symbols-visibility`
This is another case where we can simply use a rust library instead of wrangling nm.

Migrate `cross-lang-lto-clang` and `cross-lang-lto-pgo-smoketest` `run-make` tests to rmake
Part of #121876 and the associated [Google Summer of Code project](https://blog.rust-lang.org/2024/05/01/gsoc-2024-selected-projects.html).
This has the same problem outlined by #126180, where the tests do not actually run as no test-running CI enviroment has `RUSTBUILD_FORCE_CLANG_BASED_TESTS` set.
However, I still find it interesting to turn the Makefiles into the rmake format until the Clang issue is fixed.
This should technically be tested on MSVC... if MSVC actually ran Clang tests.

Migrate `symbol-visibility` `run-make` test to rmake
Part of #121876 and the associated [Google Summer of Code project](https://blog.rust-lang.org/2024/05/01/gsoc-2024-selected-projects.html).
Pretty scary!
- The expected number of symbols on each check has been changed slightly to reflect the differences between `llvm_readobj` and `nm`, as I think the former will print hidden symbols once and visible symbols twice, while the latter will only print visible symbols.
- The original test ran the same exact checks on `cdylib` twice, for seemingly no reason. I have removed it.
- This may be possible to optimize some more? `llvm_readobj` could get called only once for each library type, and the regex could avoid being created repeatedly. I am not sure if these kinds of considerations are important for a `run-make` test.
Demands a Windows try-job.

Update wasi-sdk in CI to latest release
This commit updates the `wasi-sdk` download used by the `wasm32-wasi*` targets. The motivation for this commit is generally just "keep things up to date" and is not intended to cause any issues or differences from before, just a routine update.

Disable run-make/split-debuginfo test for RISC-V 64
Together with `@Hoverbear,` we've been improving the state of the riscv64gc-unknown-linux-gnu target.
This is in relation to https://github.com/rust-lang/rust/pull/125220 where `tests/ui/debuginfo/debuginfo-emit-llvm-ir-and-split-debuginfo.rs` was disabled for RISC-V 64 in that another test, `tests/run-make/split-debuginfo` also needs to be disabled due to https://github.com/llvm/llvm-project/issues/56642 and the changes made in https://github.com/rust-lang/rust/pull/120518.
This test appears to be a host test, not a target test, so it isn't seen failing in https://github.com/rust-lang/rust/pull/126641, however, we are in the process of testing host tools for riscv64-gc-unknown-linux-gnu so this test has now been noticed to be a problem.

There are some more of these, but while the code is almost always the same, I want to keep the number reasonable so my doc comments can be inspected for potential inaccuracies. Tell me if 8 is too much, I can cut this down.

Remove extern "wasm" ABI
Remove the unstable `extern "wasm"` ABI (`wasm_abi` feature tracked in #83788).
As discussed in https://github.com/rust-lang/rust/pull/127513#issuecomment-2220410679 and following, this ABI is a failed experiment that did not end up being used for anything. Keeping support for this ABI in LLVM 19 would require us to switch wasm targets to the `experimental-mv` ABI, which we do not want to do.
It should be noted that `Abi::Wasm` was internally used for two things: The `-Z wasm-c-abi=legacy` ABI that is still used by default on some wasm targets, and the `extern "wasm"` ABI. Despite both being `Abi::Wasm` internally, they were not the same. An explicit `extern "wasm"` additionally enabled the `+multivalue` feature.
I've opted to remove `Abi::Wasm` in this patch entirely, instead of keeping it as an ABI with only internal usage. Both `-Z wasm-c-abi` variants are now treated as part of the normal C ABI, just with different different treatment in
adjust_for_foreign_abi.

Migrate `issue-83112-incr-test-moved-file`, `type-mismatch-same-crate-name` and `issue-109934-lto-debuginfo` `run-make` tests to rmake or ui
Part of #121876 and the associated [Google Summer of Code project](https://blog.rust-lang.org/2024/05/01/gsoc-2024-selected-projects.html).
I have noticed that the new UI test `debuginfo-lto-alloc` is outputting artifacts that aren't getting cleaned up because of its `-C incremental`. That might be the justification needed to keep it as a run-make test?
