Rollup merge of #126155 - Zalathar:run-make-fulldeps, r=onur-ozkan

Remove empty test suite `tests/run-make-fulldeps`

After #109770, there were only a handful of tests left in the run-make-fulldeps suite.

As of #126111, there are no longer *any* run-make-fulldeps tests, so now we can:

- Remove the directory
- Remove related bootstrap/compiletest code
- Remove various other references in CI scripts and documentation.

By removing this suite, we also no longer need to worry about discrepancies between it and ui-fulldeps, and we don't have to worry about porting tests from Makefile to [rmake](#121876) (or whether rmake even works with fulldeps).
