Rollup merge of #82269 - LeSeulArtichaut:cleanup-ppmode, r=spastorino

Cleanup `PpMode` and friends

This PR:
 - Separates `PpSourceMode` and `PpHirMode` to remove invalid states
 - Renames the variant to remove the redundant `Ppm` prefix
 - Adds basic documentation for the different pretty-print modes
 - Cleanups some code to make it more idiomatic

Not sure if this is actually useful, but it looks cleaner to me.
