Auto merge of #145717 - BoxyUwU:erase_regions_rename, r=lcnr

rename erase_regions to erase_and_anonymize_regions

I find it consistently confusing that `erase_regions` does more than replacing regions with `'erased`. it also makes some code look real goofy to be writing manual folders to erase regions with a comment saying "we cant use erase regions" :> or code that re-calls erase_regions on types with regions already erased just to anonymize all the bound regions.

r? lcnr

idk how i feel about the name being almost twice as long now
