Auto merge of #63029 - petrochenkov:rpass, r=Centril

Move run-pass tests to ui

This is the second attempt at doing https://github.com/rust-lang/rust/pull/53994 (which was previously reverted in https://github.com/rust-lang/rust/pull/54530).

The issue with inability to run the test suite in a faster way (https://github.com/rust-lang/rust/issues/54047) that motivated the revert was recently addressed by https://github.com/rust-lang/rust/pull/61755.
