Auto merge of #108233 - ChrisDenton:move-std-tests, r=thomcc

Move some std tests from `tests/ui-fulldeps` into `library/std`

This allows them to be tested normally along with other `./x test std` tests. Moving `rename_directory` is simple enough but `create_dir_all_bare` needed to be an std integration test.

Additionally, some tests that I couldn't move atm have instead been placed in an `std` subdirectory. These tests include ones that do fun things with processes or that intentionally abort the test process.
