texture_cache: cold-hint the guest memory of sparse images too

Images whose guest memory is not contiguous were left out of the cold
hint. With sparse tile remaps Mario Kart World maps its own memory into
such images, and its game memory in RAM rose by ~1.9 GB in one run. Each
mapped piece is now hinted.
