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.
Add a flat table to test if it's legal to create a texture view between
two formats or copy betweem them.
This table is based on ARB_copy_image and ARB_texture_view. Copies are
more permissive than views.
