Only use `DIST_TRY_BUILD` for try jobs that were not selected explicitly
Some CI jobs (x64 Linux, ARM64 Linux and x64 MSVC) use the `opt-dist` tool to build an optimized toolchain using PGO and BOLT. When performing a default try build for x64 Linux, in most cases we want to run perf. on that artifact. To reduce the latency of this common use-case, `opt-dist` skips building several components not needed for perf., and it also skips running post-optimization tests, when it detects that the job is executed as a try job (not a merge/auto job).
This is useful, but it also means that if you *want* to run the tests, you had to go to `jobs.yml` and manually comment this environment variable, create a WIP commit, do a try build, and then remove the WIP commit, which is annoying (in the similar way that modifying what gets run in try builds was annoying before we had the `try-job` annotations).
I thought that we could introduce some additional PR description marker like `try-job-run-tests`, but it's hard to discover that such things exist.
Instead, I think that there's a much simpler heuristic for determining whether `DIST_TRY_BUILD` should be used (that I implemented in this PR):
- If you do just ``@bors` try`, without any custom try jobs selected, `DIST_TRY_BUILD` will be activated, to finish the build as fast as possible.
- If you specify any custom try jobs, you are most likely doing experiments and you want to see if tests pass and everything builds as it should. The `DIST_TRY_BUILD` variable will thus *not* be set in this case.
In this way, if you want to run dist tests, you can just add the `try-job: dist-x86_64-linux` line to the PR description, and you don't need to create any WIP commits.

Continuing the work from #137350.
Removes the unused methods: `expect_variant`, `expect_field`,
`expect_foreign_item`.
Every method gains a `hir_` prefix.
Retire the legacy `Makefile`-based `run-make` test infra
The final piece of [porting run-make tests to use Rust #121876](https://github.com/rust-lang/rust/issues/121876).
Closes#121876.
Closes#40713.
Closes#81791 (no longer using `wc`).
Closes#56475 (no longer a problem in current form of that test; we don't ignore the test on `aarch64-unknown-linux-gnu`).
### Summary
This PR removes the legacy `Makefile`-based `run-make` test infra which has served us well over the years. The legacy infra is no longer needed since we ported all of `Makefile`-based `run-make` tests to the new `rmake.rs` infra.
Additionally, this PR:
- Removes `tests/run-make/tools.mk` since no more `Makefile`-based tests remain.
- Updates `tests/run-make/README.md` and rustc-dev-guide docs to remove mention about `Makefile`-based `run-make` tests
- Update test suite requirements in rustc-dev-guide on Windows to no longer need MSYS2 (they should also now run successfully on native Windows MSVC).
- Update `triagebot.toml` to stop backlinking to #121876.
**Thanks to everyone who helped in this effort to modernize the `run-make` test infra and test suite!**

Support raw-dylib link kind on ELF
raw-dylib is a link kind that allows rustc to link against a library without having any library files present.
This currently only exists on Windows. rustc will take all the symbols from raw-dylib link blocks and put them in an import library, where they can then be resolved by the linker.
While import libraries don't exist on ELF, it would still be convenient to have this same functionality. Not having the libraries present at build-time can be convenient for several reasons, especially cross-compilation. With raw-dylib, code linking against a library can be cross-compiled without needing to have these libraries available on the build machine. If the libc crate makes use of this, it would allow cross-compilation without having any libc available on the build machine. This is not yet possible with this implementation, at least against libc's like glibc that use symbol versioning. The raw-dylib kind could be extended with support for symbol versioning in the future.
This implementation is very experimental and I have not tested it very well. I have tested it for a toy example and the lz4-sys crate, where it was able to successfully link a binary despite not having a corresponding library at build-time.
I was inspired by Björn's comments in https://internals.rust-lang.org/t/bundle-zig-cc-in-rustup-by-default/22096/27

Rewrite the `ci.py` script in Rust
It would seem that I would learn by now that any script written in Python will become unmaintainable sooner or later, but alas..

stabilize stage management for rustc tools
https://github.com/rust-lang/rust/pull/135990 got out of control due to excessive complexity. This PR aims to achieve the same goal with a simpler approach, likely through multiple smaller PRs. I will keep the other one read-only and open as a reference for future work.
This work stabilizes the staging logic for `ToolRustc` programs, so you no longer need to handle build and target compilers separately in steps. Previously, most tools didn't do this correctly, which was causing the compiler to be built twice (e.g., `x test cargo --stage 1` would compile the stage 2 compiler before, but now it only compiles the stage 1 compiler).
I also tried to document how we should write `ToolRustc` steps as they are quite different and require more attention than other tools.
Next goal is to stabilize how stages are handled for the rustc itself. Currently, `x build --stage 1` builds the stage 1 compiler which is fine, but `x build compiler --stage 1` builds stage 2 compiler.

Added project-specific Zed IDE settings
This repository currently has project-specific VS Code IDE settings in `.vscode` and `compiler/rustc_codegen_cranelift/.vscode`. Now there are equivalent project-specific Zed IDE settings alongside those.
This fixes `rust-analyzer` not being able to properly handle this project.
Note that:
1. The contents of `src/tools/rust-analyzer/.vscode` could not be translated to Zed, as they aren't basic IDE settings.
2. One of the VS Code settings in `.vscode` has no corresponding setting in Zed, and so this has been noted like this:
```json
"_settings_only_in_vs_code_not_yet_in_zed": {
"git.detectSubmodulesLimit": 20
},
```
