gdb: scope down registers_changed call in inferior::set_arch

Browse Source 
inferior::set_arch calls registers_changed, which invalidates all
regcaches.  It would be enough to invalidate only regcaches of threads
belonging to this inferior.  Call registers_changed_ptid instead, with
the proper process target / ptid.  If the inferior does not have a
process target, there should be no regcaches for that inferior, so no
need to invalidate anything.
