13606a6d0b Memory: Remove count of cached pages and add InvalidateRegion
In a future commit, the count of cached pages will be reintroduced in
the actual surface cache. Also adds an Invalidate only to the cache
which marks a region as invalid in order to try to avoid a costly flush
from 3ds memory

35da7f57ef Memory: Allow IsValidVirtualAddress to be called with a specific process parameter.
There is still an overload of IsValidVirtualAddress that only takes the VAddr and will default to the current process.

41f6c9f87f 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.

d553135748 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.

f2a5a77e27 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.

f2b9be9bd3 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.

ebdae19fd2 Remove empty newlines in #include blocks.
This makes clang-format useful on those.

Also add a bunch of forgotten transitive includes, which otherwise
prevented compilation.

memory management functions will be built.
