Coalesce `dep-info`, `dep-info-spaces` and `dep-info-doesnt-run-much` `run-make` tests into `dep-info` rmake.rs

Part of rust-lang#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](rust-lang@0d9fd8e) that added the `sleep`).

I tried to preserve the intent of the test, which is smoke-testing that `dep-info` works.

Only try to modify file times of a writable file on Windows

Introduces a `set_file_times` helper which opens a given path as a file in r+w mode on Windows and then sets file times. Previously the file was open as read-only for Windows which caused permission errors locally.

This should hopefully make setting file times less error prone, since trying to set file times on read-only file on Windows also happened in rust-lang#127850.

Port `run-make/libtest-json` and `run-make/libtest-junit` to rmake

Unlike rust-lang#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 rust-lang#121876.

Port the `sysroot-crates-are-unstable` Python script to rmake

New version of rust-lang#126231, and a follow-up to rust-lang#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 rust-lang#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 rust-lang#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.
