Auto merge of #54223 - pnkfelix:issue-53764-uiify-run-pass, r=nikomatsakis

`ui`ify run-pass

This addresses the remainder of #53764 by first converting `src/test/run-pass` into another `ui`-style test suite, and then turning on `compare-mode=nll` for that new suite.

After this lands, we can address #54047 for the short term by moving all the `src/test/ui/run-pass` tests back to `src/test/run-pass`.

(Longer term, the compiler team's current (hypothetical sketch of a) plan (see [1][], [2][]) is unify all the tests by embedding these meta-properties like "// run-pass` into their headers explicitly and dropping the significance of their location on the file system.)
