core: Add asserts for region free-list locking
This change adds asserts to the mem_region calls that should have the
per-region lock held.
To keep the tests working, they need the lock_held_by_me() function. The
run-mem_region.c test has a bogus implementation of this, as it doesn't
do any locking at the moment. This will be addressed in a later change.
