Memory/RasterizerCache: Ignore unmapped memory regions when caching physical regions.
...
Not all physical regions need to be mapped into the address space of every process, for example, system modules do not have a VRAM mapping.
This fixes a crash when loading applets and system modules.

Memory: Add function to flush a virtual range from the rasterizer cache
...
This is slightly more ergonomic to use, correctly handles virtual
regions which are disjoint in physical addressing space, and checks only
regions which can be cached by the rasterizer.

Memory: Fix crash when unmapping a VMA covering cached surfaces
...
Unmapping pages tries to flush any cached GPU surfaces touching that
region. When a cached page is invalidated, GetPointerFromVMA() is used
to restore the original pagetable pointer. However, since that VMA has
already been deleted, this hits an UNREACHABLE case in that function.
Now when this happens, just set the page type to Unmapped and continue,
which arrives at the correct end result.

Memory: Always flush whole pages from surface cache
...
This prevents individual writes touching a cached page, but which don't
overlap the surface, from constantly hitting the surface cache lookup.
