Port the `sysroot-crates-are-unstable` Python script to rmake
New version of #126231, and a follow-up to #129071.
One major difference is that the new version no longer tries to report *all* accidentally-stable crates, because the `run_make_support` helpers tend to halt the test as soon as something goes wrong. That's unfortunate, but I think it won't matter much in practice, and preserving the old behaviour doesn't seem worth the extra effort.
---
Part of #110479 (Python purge), with this being one of the non-trivial Python scripts that actually seems feasible and worthwhile to remove.
This is *not* part of #121876 (Makefile purge), because the underlying test is already using rmake; this PR just modifies the existing rmake recipe to do all the work itself instead of delegating to Python. So there's no particular urgency here.

Port `run-make/libtest-json` and `run-make/libtest-junit` to rmake
Unlike #126773, this is just a straightforward port to `rmake`, without attempting to switch to compiletest or get rid of the (trivial) Python scripts.
Part of #121876.

Coalesce `dep-info`, `dep-info-spaces` and `dep-info-doesnt-run-much` `run-make` tests into `dep-info` rmake.rs
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 is one of the most ancient tests in the `run-make` directory and its Makefile does some unexpected things, like creating and deleting a `done` directory over and over, sleeping at certain times (this is the [commit](0d9fd8e2a1) that added the `sleep`).
I tried to preserve the intent of the test, which is smoke-testing that `dep-info` works.

Remove duplicated `Rustdoc::output` method from `run-make-support` lib
I discovered recently that `--output` is deprecated in rustdoc and that `--out-dir` is doing the exact same thing. To keep things along with the current rustdoc status, I removed the `Rustdoc::output` method.

Add possibility to generate rustdoc JSON output to stdout
Fixes#127165.
I think it's likely common to want to get rustdoc json output directly instead of reading it from a file so I added this option to allow it. It's unstable and only works with `--output-format=json`.

Port `run-make/sysroot-crates-are-unstable` to rmake
I already have a more elaborate draft at #126231 that tries to port the underlying Python script to rmake, but there's no need for the removal of Makefiles to be held up on complex tasks like that, so this PR simply takes the trivial Makefile and converts it into a trivial rmake recipe.
Part of #121876.

Fix warnings in rmake tests on `x86_64-unknown-linux-gnu`
r? `@jieyouxu`
This PR fixes some warnings I saw in rmake tests. I didn't deny more warnings in this PR until `@jieyouxu` gives their opinion, but maybe we should actually deny all warnings in `rmake.rs` files?
I've also only looked at non-ignored tests on `x86_64-unknown-linux-gnu`, and denying warnings would require a try build for all targets 😓.
run-make: explaing why fmt-write-bloat is ignore-windows
The trouble here is that libc doesn't exist on Windows. Well it kinda does but it isn't called that so we substitute a name that works. Ideally finding necessary libs for the platform would be done at a higher level but until then this should work.

run-make: enable msvc for staticlib-dylib-linkage
`-Zstaticlib-allow-rdylib-deps` on MSVC returns things like `/LIBPATH:R:\rust\build\x86_64-pc-windows-msvc\test\run-make\staticlib-dylib-linkage\rmake_out`. That is a linker argument rather than a `cc` argument. Which makes sense because rustc interacts directly with the linker on MSVC targets. So we need to tell the C compiler to pass on the arguments to the linker.

run-make: enable msvc for redundant-libs
The issue here was that `foo` was not exporting any functions therefore creating an import library was unnecessary and elided by the linker.
I fixed it by exporting the functions.
