Alexander Potapenko 3429055f04 mm: kmsan: implement kmsan_memmove()
Provide a hook that can be used by custom memcpy implementations to tell
KMSAN that the metadata needs to be copied.  Without that, false positive
reports are possible in the cases where KMSAN fails to intercept memory
initialization.
