Migrate `remap-path-prefix-dwarf` `run-make` test to rmake

Possibly my proudest branch name yet.

When a type comes indirectly from one crate version but the imported trait comes from a separate crate version, the called method won't be found. We now show additional context:
```
error[E0599]: no method named `foo` found for struct `dep_2_reexport::Type` in the current scope
--> multiple-dep-versions.rs:8:10
|
8 | Type.foo();
| ^^^ method not found in `Type`
|
note: you have multiple different versions of crate `dependency` in your dependency graph
--> multiple-dep-versions.rs:4:32
|
4 | use dependency::{do_something, Trait};
| ^^^^^ `dependency` imported here doesn't correspond to the right crate version

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.

Add tests to ensure MTE tags are preserved across FFI boundaries
Added run-make tests to verify that, between a Rust-C FFI boundary in both directions, any MTE tags included in a pointer are preserved for the following pointer types, as well as any information stored using TBI:
- int
- float
- string
- function

Migrate `pgo-gen-lto` `run-make` test to rmake

This one is so easy, I'm surprised I missed it.

Enable msvc for run-make/rust-lld
This is simply a matter of using the right argument for lld-link.
As a bonus, I also fixed a typo.

Migrate `cross-lang-lto-upstream-rlibs`, `long-linker-command-lines` and `long-linker-command-lines-cmd-exe` `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).
The `long-linker` tests are certainly doing something... interesting - they summon `rustc` calls with obscene quantities of arguments and check that this is appropriately handled. I removed the `RUSTC_ORIGINAL` magic - it's equivalent to `RUSTC` in `tools.mk`, so what is the purpose? Making it so the massive pile of flags doesn't modify rustc itself and start leaking into other tests? Tell me what you think.

run-make: Enable msvc for `no-duplicate-libs` and `zero-extend-abi-param-passing`
The common thing between these two tests is to use `#[link(..., kind="static")]` so that it doesn't try to do a DLL import.
`zero-extend-abi-param-passing` also needs to have an optimized static library but there's only helper function for a non-optimized version. Rather than copy/pasting the code (and adding the optimization flag) I reused the same code so that it more easily be kept in sync.

Enable msvc for link-args-order
I could not see any reason in #70665 why this test needs to specifically use `ld`. Maybe to provide a consistent linker input line? In any case, the test does work for the MSVC linker.

run-make: enable msvc for `link-dedup`
This is just a case of differing style of linker arguments.
I also cleaned up a bit where we were running the same command three times in a row. Instead I reused the output.
One thing that confused me is why we were testing for the same lib three times in a row but not two. After figuring that out I added a note to hopefully save future readers some confusion.
