51927bc9dc kernel/physical_core: Remove unused kernel reference member variable
This isn't used within the class, so it can be removed to simplify the
overall interface.

While we're in the same area, we can simplify a unique_ptr reset() call.

c76ffa5019 core/kernel: Fix GetTotalPhysicalMemoryUsed.
module._memory was already moved over to a new shared_ptr.
So code_memory_size was not increased at all.

This lowers the heap space and so saves a bit of memory, usually between 50 to 100 MB.

This fixes a regression of c0a01f3adc

67b8265bd6 kernel/svc: Provide implementations for svcDumpInfo/svcDumpInfoNew
These are fairly trivial to implement, we can just do nothing. This also
provides a spot for us to potentially dump out any relevant info in the
future (e.g. for debugging purposes with homebrew, etc).

While we're at it, we can also correct the names of both of these
supervisor calls.

e7e939104b core/memory; Migrate over SetCurrentPageTable() to the Memory class

e4c381b885 core/memory: Migrate over Write{8, 16, 32, 64, Block} to the Memory class
The Write functions are used slightly less than the Read functions,
which make these a bit nicer to move over.

The only adjustments we really need to make here are to Dynarmic's
exclusive monitor instance. We need to keep a reference to the currently
active memory instance to perform exclusive read/write operations.

b05bfc6036 core/memory: Migrate over Read{8, 16, 32, 64, Block} to the Memory class
With all of the trivial parts of the memory interface moved over, we can
get right into moving over the bits that are used.

Note that this does require the use of GetInstance from the global
system instance to be used within hle_ipc.cpp and the gdbstub. This is
fine for the time being, as they both already rely on the global system
instance in other functions. These will be removed in a change directed
at both of these respectively.

For now, it's sufficient, as it still accomplishes the goal of
de-globalizing the memory code.

A fairly straightforward migration. These member functions can just be

plumbing in places that they're used.

doesn't rely on class state in any form.

Prior to PR, Yuzu did not restore memory to RW-
on unmap of mirrored memory or unloading of NRO.

(In fact, in the NRO case, the memory was unmapped

actually lost entirely...)

This PR addresses that, and restores memory to RW-
as it should.

13a8fde3ad Implement MapPhysicalMemory/UnmapPhysicalMemory
This implements svcMapPhysicalMemory/svcUnmapPhysicalMemory for Yuzu,
which can be used to map memory at a desired address by games since
3.0.0.

It also properly parses SystemResourceSize from NPDM, and makes
information available via svcGetInfo.

This is needed for games like Super Smash Bros. and Diablo 3 -- this
PR's implementation does not run into the "ASCII reads" issue mentioned
in the comments of #2626, which was caused by the following bugs in
Yuzu's memory management that this PR also addresses:
* Yuzu's memory coalescing does not properly merge blocks. This results
  in a polluted address space/svcQueryMemory results that would be
  impossible to replicate on hardware, which can lead to game code making
  the wrong assumptions about memory layout.
  * This implements better merging for AllocatedMemoryBlocks.
* Yuzu's implementation of svcMirrorMemory unprotected the entire
  virtual memory range containing the range being mirrored. This could
  lead to games attempting to map data at that unprotected
  range/attempting to access that range after yuzu improperly unmapped
  it.
  * This PR fixes it by simply calling ReprotectRange instead of
    Reprotect.
