kmsan: enter the runtime around kmsan_internal_memmove_metadata() call
kmsan_internal_memmove_metadata() transitively calls stack_depot_save()
(via kmsan_internal_chain_origin() and kmsan_save_stack_with_flags()),
which may allocate memory. Guard it with kmsan_enter_runtime() and
kmsan_leave_runtime() to avoid recursion.
