Use scope_exit in regcache.c
This removes the regcache_invalidator class in favor of a scope_exit.
This seems like an improvement (albeit a minor one) because
regcache_invalidator is only used in a single spot.
gdb/ChangeLog:

* regcache.c (class regcache_invalidator): Remove.
(regcache::raw_write): Use make_scope_exit.
