Rollup merge of rust-lang#79038 - CDirkx:move-ui-tests, r=dtolnay

Change ui test that are run-pass and that do not test the compiler to library tests

Part of rust-lang#76268, these are some of the relevant ui tests I found that can be replaced by library tests.

Note: this PR just moves the tests, I have not checked for any overlap between these tests and existing library tests. The only test I changed is `env_home_dir`, where I added code to restore the old home dir after testing.

All moved tests:
