Rewrite `suspicious-library`, `resolve-rename` and `incr-prev-body-beyond-eof` `run-make` tests in `rmake.rs` format
Part of #121876 and the associated [Google Summer of Code project](https://blog.rust-lang.org/2024/05/01/gsoc-2024-selected-projects.html).
Some oddly specific ignore flags in `incr-prev-body-beyond-eof`:
```rs
// ignore-none
// ignore-nvptx64-nvidia-cuda
```
it could be interesting to run a try job, but it seems there is no nvidia-cuda in the CI settings (`jobs.yml`).

Update `compiler-builtins` test to not clear essential env vars
Noticed in https://github.com/rust-lang/rust/pull/122580#issuecomment-2125755689, the `compiler-builtins` test failed on Windows for a `cargo` invocation because necessary env vars `TMP` and `TEMP` were cleared by `Command::env_clear`, causing temp dir eventually used by codegen to fallback to the Windows directory, which will trigger permission errors.
This PR removes the `env_clear` on the cargo invocation.

Handle no values cfgs with `--print=check-cfg`
This PR fix a bug with `--print=check-cfg`, where no values cfgs where not printed since we only printed cfgs that had at least one values.
The representation I choose is `CFG=`, since it doesn't correspond to any valid config, it also IMO nicely complements the `values()` (to indicate no values). Representing the absence of value by the absence of the value.
So for `cfg(feature, values())` we would print `feature=`.
I also added the missing tracking issue number in the doc.

Show files produced by `--emit foo` in json artifact notifications
Right now it is possible to ask `rustc` to save some intermediate representation into one or more files with `--emit=foo`, but figuring out what exactly was produced is difficult. This pull request adds information about `llvm_ir` and `asm` intermediate files into notifications produced by `--json=artifacts`.
Related discussion: https://internals.rust-lang.org/t/easier-access-to-files-generated-by-emit-foo/20477
Motivation - `cargo-show-asm` parses those intermediate files and presents them in a user friendly way, but right now I have to apply some dirty hacks. Hacks make behavior confusing: https://github.com/hintron/computer-enhance/issues/35
This pull request introduces a new behavior: now `rustc` will emit a new artifact notification for every artifact type user asked to `--emit`, for example for `--emit asm` those will include all the `.s` files.
Most users won't notice this behavior, to be affected by it all of the following must hold:
- user must use `rustc` binary directly (when `cargo` invokes `rustc` - it consumes artifact notifications and doesn't emit anything)
- user must specify both `--emit xxx` and `--json artifacts`
- user must refuse to handle unknown artifact types
- user must disable incremental compilation (or deal with it better than cargo does, or use a workaround like `save-temps`) in order not to hit #88829 / #89149
With the exception of `tests/run-make/translation/test.rs`, which has a
syntax error.
The expected output in `rustdoc-error-lines/rmake.rs`'s required slight
tweaking.
The two `reproducible-build.rs` files need `// ignore-tidy-linelength`
because rustfmt produces lines longer than 100 chars, which tidy doesn't
like, yuk.

Make more of the test suite run on Mac Catalyst
Combined with https://github.com/rust-lang/rust/pull/125225, the only failing parts of the test suite are in `tests/rustdoc-js`, `tests/rustdoc-js-std` and `tests/debuginfo`. Tested with:
```console
./x test --target=aarch64-apple-ios-macabi library/std
./x test --target=aarch64-apple-ios-macabi --skip=tests/rustdoc-js --skip=tests/rustdoc-js-std --skip=tests/debuginfo tests
```
Will probably put up a PR later to enable _running_ on (not just compiling for) Mac Catalyst in CI, though not sure where exactly I should do so? `src/ci/github-actions/jobs.yml`?
Note that I've deliberately _not_ enabled stack overflow handlers on iOS/tvOS/watchOS/visionOS (see https://github.com/rust-lang/rust/issues/25872), but rather just skipped those tests, as it uses quite a few APIs that I'd be weary about getting rejected by the App Store (note that Swift doesn't do it on those platforms either).
