Auto merge of #54530 - pnkfelix:issue-54047-migrate-ui-run-pass-back-to-run-pass, r=alexcrichton

Migrate `src/test/ui/run-pass/*` back to `src/test/run-pass/`.

Moves all the tests from `src/test/ui/run-pass/**` back to `src/test/run-pass/`.

This should have no impact on our overall testing completeness due to PR #54223

Fix #54047

+// On MSVC we have a "hack" where we emit symbols that look like `_imp_$name`
+// for all exported statics. This is done because we apply `dllimport` to all
+// imported constants and this allows everything to actually link correctly.
+//
+// The ThinLTO passes aggressively remove symbols if they can, and this test
+// asserts that the ThinLTO passes don't remove these compiler-generated
+// `_imp_*` symbols. The external library that we link in here is compiled with
+// ThinLTO and multiple codegen units and has a few exported constants. Note
+// that we also namely compile the library as both a dylib and an rlib, but we
+// link the rlib to ensure that we assert those generated symbols exist.
