Subject: [PATCH 01/13] core/memory: Introduce skeleton of Memory class
Currently, the main memory management code is one of the remaining
places where we have global state. The next series of changes will aim
to rectify this.
This change simply introduces the main skeleton of the class that will
contain all the necessary state.

Subject: [PATCH 02/13] core/memory: Migrate over memory mapping functions to
the new Memory class
Migrates all of the direct mapping facilities over to the new memory
class. In the process, this also obsoletes the need for memory_setup.h,
so we can remove it entirely from the project.

Subject: [PATCH 03/13] core/memory: Migrate over address checking functions to
the new Memory class
A fairly straightforward migration. These member functions can just be
mostly moved verbatim with minor changes. We already have the necessary
plumbing in places that they're used.
IsKernelVirtualAddress() can remain a non-member function, since it
doesn't rely on class state in any form.

Subject: [PATCH 04/13] core/memory: Move memory read/write implementation
functions into an anonymous namespace
These will eventually be migrated into the main Memory class, but for
now, we put them in an anonymous namespace, so that the other functions
that use them, can be migrated over separately.

Subject: [PATCH 05/13] core: Prepare various classes for memory read/write
migration
Amends a few interfaces to be able to handle the migration over to the
new Memory class by passing the class by reference as a function
parameter where necessary.
Notably, within the filesystem services, this eliminates two ReadBlock()
calls by using the helper functions of HLERequestContext to do that for
us.

Subject: [PATCH 09/13] core/memory: Migrate over ZeroBlock() and CopyBlock()
to the Memory class
These currently aren't used anywhere in the codebase, so these are very
trivial to move over to the Memory class.

Subject: [PATCH 10/13] 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.

Subject: [PATCH 11/13] 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.

Now that everything else is migrated over, this is essentially just code
relocation and conversion of a global accessor to the class member
variable.
All that remains is to migrate over the page table.

Subject: [PATCH 13/13] core/memory; Migrate over SetCurrentPageTable() to the
Memory class
Now that literally every other API function is converted over to the
Memory class, we can just move the file-local page table into the Memory
implementation class, finally getting rid of global state within the
memory code.
