Auto merge of #109875 - jyn514:no-fulldeps, r=compiler-errors

Move most ui-fulldeps tests to ui/

Same rationale as rust-lang/rust#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; rust-lang/rust#109873 makes up for it.
