5159f4eee8 Memory: don't lock hle mutex in memory read/write 
The comment already invalidates itself: neither MMIO nor rasterizer cache belongsHLE kernel state. This mutex has a too large scope if MMIO or cache is included, which is prone to dead lock when multiple thread acquires these resource at the same time. If necessary, each MMIO component or rasterizer should have their own lock.

ef84c70d22 Speed up memory page mapping (#2141) 
- Memory::MapPages total samplecount was reduced from 4.6% to 1.06%.
- From main menu into the game from 1.03% to 0.35%

fdd649e2ef Fixed uninitialized memory due to missing returns in canary 
Functions which are suppose to crash on non canary builds usually don't return anything which lead to uninitialized memory being used.

15e3d4f357 memory: Convert ASSERT into a DEBUG_ASSERT within GetPointerFromVMA() 
Given memory should always be expected to be valid during normal
execution, this should be a debug assertion, rather than a check in
regular builds.

d4c1b9d311 vm_manager: Make vma_map private 
This was only ever public so that code could check whether or not a
handle was valid or not. Instead of exposing the object directly and
allowing external code to potentially mess with the map contents, we
just provide a member function that allows checking whether or not a
handle is valid.

This makes all member variables of the VMManager class private except
for the page table.

cf9d6c6f52 kernel/process: Make data member variables private 
Makes the public interface consistent in terms of how accesses are done
on a process object. It also makes it slightly nicer to reason about the
logic of the process class, as we don't want to expose everything to
external code.

83377113bf memory: Dehardcode the use of fixed memory range constants 
The locations of these can actually vary depending on the address space
layout, so we shouldn't be using these when determining where to map
memory or be using them as offsets for calculations. This keeps all the
memory ranges flexible and malleable based off of the virtual memory
manager instance state.

45fb74d262 gpu: Make memory_manager private 
Makes the class interface consistent and provides accessors for
obtaining a reference to the memory manager instance.

Given we also return references, this makes our more flimsy uses of
const apparent, given const doesn't propagate through pointers in the
way one would typically expect. This makes our mutable state more
apparent in some places.

2665457f4a renderer_base: Make Rasterizer() return the rasterizer by reference 
All calling code assumes that the rasterizer will be in a valid state,
which is a totally fine assumption. The only way the rasterizer wouldn't
be is if initialization is done incorrectly or fails, which is checked
against in System::Init().

6030c5ce41 video_core: Eliminate the g_renderer global variable 
We move the initialization of the renderer to the core class, while
keeping the creation of it and any other specifics in video_core. This
way we can ensure that the renderer is initialized and doesn't give
unfettered access to the renderer. This also makes dependencies on types
more explicit.

For example, the GPU class doesn't need to depend on the
existence of a renderer, it only needs to care about whether or not it
has a rasterizer, but since it was accessing the global variable, it was
also making the renderer a part of its dependency chain. By adjusting
the interface, we can get rid of this dependency.

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.
