rustc_attr_ir: fix up imports

[mejrs]

Cleanup after splitting attributes from rustc_hir.

It's a big one and maybe annoying to merge without conflicts but I figured it's best to just get it done and over with. If it turns out to be too big to merge at once it should be possible to split it up tho :>
