[dev.regabi] cmd/compile: replace NodeQueue with NameQueue

Similar to the previous CL, the only two users of NodeQueue only
needed it for tracking objects, not arbitrary AST nodes. So change
it's signature to use *Name instead of Node.

This does require a tweak to the nowritebarrierrec checker, because
previously it was pushing the ODCLFUNC *Func pointers into the queue,
whereas now we push the ONAME/PFUNC *Name pointers instead. However,
it's trivial and safe to flip between them.

Also, this changes a handful of export-related code from Node to
*Name, to avoid introducing type assertions within iexport.go.

Passes buildall w/ toolstash -cmp.

Updates #42982.
