Rollup merge of #110918 - ChrisDenton:on-error-resume-next, r=cuviper

`remove_dir_all`: try deleting the directory even if `FILE_LIST_DIRECTORY` access is denied

If opening a directory with `FILE_LIST_DIRECTORY` access fails then we should try opening without requesting that access. We may still be able to delete it if it's empty or a link.

Fixes rust-lang/cargo#12042
