cmd/internal/obj: consolidate emitting entry stack map

Browse source 
The obj package needs to emit the PCDATA to select the entry stack map
before calling morestack. Currently this is copied for every
architecture. Since we're about to change how this works, consolidate
all of these copies into a single helper function.

For #24543.
