cache: Invalidate pages for file reads. (#1726)

* cache: Invalidate pages for file reads.

* texture_cache: Simplify invalidate intersection check.

* vk_rasterizer: Make aware of mapped memory ranges.

* buffer_cache: Remove redundant page calculations.

Called functions will convert to page numbers/addresses themselves.

* file_system: Simplify memory invalidation and add a few missed cases.
