ReinUsesLisp 9764c13d6d video_core: Rewrite the texture cache
The current texture cache has several points that hurt maintainability
and performance. It's easy to break unrelated parts of the cache
when doing minor changes. The cache can easily forget valuable
information about the cached textures by CPU writes or simply by its
normal usage.The current texture cache has several points that hurt

This commit aims to address those issues.
