Move most ui-fulldeps tests to ui/ Same rationale as https://github.com/rust-lang/rust/pull/109770, they don't actually need a stage 2 build. This increases the limit for the UI directory because otherwise it was annoying to be constantly moving files into subdirectories when I fixed a test; https://github.com/rust-lang/rust/pull/109873 makes up for it. cc https://github.com/rust-lang/rust/pull/109770, https://github.com/rust-lang/rust/pull/109874
