Updates #118698

Add some ui tests for parallel rustc front end

This is a relatively large feature so I think it's worth creating a new entity in tests/ui folder, so we need to modify the limit in tidy.

Thanks for the PR, @SparrowLii!

It looks like we don't have a parallelization group in triagebot.toml. Do you know a reviewer with the necessary context?

How will we deal with spurious failures of these in CI that only happen every 10th/100th run or so?

Some use cases can be tested multiple times (such as 10 or 100 times) by modifying the compile-test tool, but there are still some errors (such as once in 10000 times) that are difficult to guarantee correct.

So I think this PR is just the beginning

Maybe we can also increase the threadcount to 50 or so to increase the chance of concurrency problems?

Yeah of course we should.

We can add some simple use cases first to ensure that the basic functions will not be overturned (such as #118648)

The no ImplicitCtxt stored in tls error showed here so I think we need to solve #111522 first :(

Otherwise we cannot guarantee the stability of the test results

The reason for this error is that the test case workerlocal-outer-thread-pool-issue-94654.rs relies on the deadlock_handler function (since it has queries cycle error), which triggers the error in #111522. Other test cases should not be affected.

I think the commits should be squashed together before merging. Otherwise, more tests is good. It seems like the concern from yesterday has been resolved? If so, r=me once the commits are squashed.

Thanks! We need to enhance the ui testing tool to support more tests (I listed it in #118698), so I would like to add them in another new PR
