3cb2bf08c3 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.

bfc70ef1d1 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.

36100ec791 Kernel/Memory: Give each Process its own page table.

Kernel/HLE: Use a mutex  to synchronize access to the HLE kernel state between the cpu thread and any other possible threads that might touch the kernel (network thread, etc).

1423b3b10e 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.

3bc1034465 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.

415064165a 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.

1138ec0d49 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.

in the future. It also adds support for different system memory types

0a60aa75c2 Kernel: Add VMManager to manage process address spaces 
This enables more dynamic management of the process address space,
compared to just directly configuring the page table for major areas.

This will serve as the foundation upon which the rest of the Kernel
memory management functions will be built.
