Update extern linking documentation
In particular, remove the note saying cdylibs can't link against dylibs — that hasn't been true for over four years.

Migrate `issue-85401-static-mir`, `missing-crate-dependency` and `unstable-flag-required` `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).

Const-to-pattern-to-MIR cleanup
Now that all uses of constants without structural equality are hard errors, there's a bunch of cleanup we can do in the code that handles patterns: we can always funnel patterns through valtrees first (rather than having a fallback path for when valtree construction fails), and we can make sure that if we emit a `PartialEq` call it is not calling anything user-defined.
To keep the error messages the same, I made valtree construction failures return the information of *which* type it is that cannot be valtree'd. `search_for_structural_match_violation` is now not needed any more at all, so I removed it.

Migrate 8 very similar FFI `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).
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.
For the tracking issue:
- issue-25581
- extern-fn-with-extern-types
- extern-fn-struct-passing-abi
- longjmp-across-rust
- static-extern-type
- extern-fn-explicit-align
- extern-fn-with-packed-struct
- extern-fn-mangle
Migrate `atomic-lock-free` to `rmake`
Also adds `llvm_components_contain` to `run-make-support`.

style-guide: Clarify version-sorting
Every time we apply version-sorting, we also say to sort non-lowercase before
lowercase. This seems likely to be what we'll want for future sorting,
as well. For simplicity, just incorporate that into the definition,
"unless otherwise specified".
Commonize `uname -m` results for `aarch64` in docker runner
`uname -m` on Linux reports `aarch64`, but on MacOS reports `arm64`. Commonize this to `aarch64`.
With this fix, it is now possible to run aarch64 CI docker images on Arm MacOS.

Reorganize the `run-make-support` library
The `run_make_support` library has a kitchen sink `lib.rs` that make discovery/learning very difficult. Let's try to improve that by breaking up `lib.rs` into smaller more organized modules. This is a precursor to improving the documentation and learnability of the `run_make_support` library.
### Changes
- Breakup `lib.rs` into smaller modules according to functionality
- Rename `recursive_diff` -> `assert_dirs_are_equal`
- Rename one of the `read_dir` with callback interface as `read_dir_entries`
- Coalesced fs-related stuff onto a `fs` module, re-exported to tests as `rfs`
- Minor doc improvements / fixes in a few places (I have a follow-up documentation PR planned)
This PR is best reviewed commit-by-commit.

There were *two* `read_dir` helpers, one being a simple
`std::fs::read_dir` wrapper, the other has a different callback-based
signature. We also rename the callback-based `read_dir` as
`read_dir_entries`.
Also don't top-level re-export most `fs::*` helpers.
