Take revision into account in non-incremental-mode `// incremental` tests

A UI test I added in #105983 confusingly [failed](https://github.com/rust-lang/rust/pull/106031#issuecomment-1362558067) in a merge because two different revisions raced with each other for the same incremental directory for a (non-incremental-mode, i.e. `src/test/ui`) UI test.

Let's take the revision name into account when generating an incremental directory so that other UI tests that combine `// incremental` and `// revisions` won't race and cause possible flakiness in CI.
