These are holdovers from Citra.

We need to ensure dynarmic gets a valid pointer if the page table is
resized (the relevant pointers would be invalidated in this scenario).

In this scenario, the page table can be resized depending on what kind
of address space is specified within the NPDM metadata (if it's
present).

In our error console, when loading a game, the strings:

QString::arg: Argument missing: "Loading...", 0
QString::arg: Argument missing: "Launching...", 0

would occasionally pop up when the loading screen was running. This was
due to the strings being assumed to have formatting indicators in them,
however only two out of the four strings actually have them.

This only applies the arguments to the strings that have formatting
specifiers provided, which avoids these warnings from occurring.

This commit makes sure GL reads on the correct pack size for the
respective texture buffer.

These are holdovers from Citra and can be removed.

Now that nothing actually touches the internal page table aside from the
memory subsystem itself, we can remove the accessor to it.

Given the page table will always be guaranteed to be that of whatever
the current process is, we no longer need to keep this around.

Centralizes the page table switching to one spot, rather than making
calling code deal with it everywhere.

Keeps the return type consistent with the function name. While we're at
it, we can also reduce the amount of boilerplate involved with handling
these by using structured bindings.

Returns the same type that the function name describes.

Avoids dragging in a direct dependency in a header.

Nothing in this header relies on common_funcs or the memory manager.

This gets rid of reliance on indirect inclusions in the OpenGL caches.

This doesn't actually work anymore, and given how long it's been left in
that state, it's unlikely anyone actually seriously used it.

Generally it's preferable to use RenderDoc or Nsight to view surfaces.

We can just use .at(), which essentially does the same thing, but with
less code.

Given we already ensure nothing can set the zeroth register in
SetRegister(), we don't need to check if the index is zero and special
case it. We can just access the register normally, since it's already
going to be zero.

We can also replace the assertion with .at() to perform the equivalent
behavior inline as part of the API.

Given this doesn't actually alter internal state, this can be made a
const member function.

Now, since we have a const qualified variant of GetPointer(), we can put
it to use in ReadBlock() to retrieve the source pointer that is passed
into memcpy.

Now block reading may be done from a const context.

Allows retrieving read-only pointers from a const context externally.

This doesn't modify internal state, so it can be made a const member
function.

This doesn't modify any internal state, so it can be made a const member
function to allow its use in const contexts.

- Use QStringLiteral where applicable.

- Use const where applicable

- Remove unnecessary precondition check (we already assert the pixbuf
  being non null)

We can utilize qOverload with the signal connections to make the
function deducing a little less ugly.

Fills in the missing surface types that were marked as unknown. The
order corresponds with the TextureFormat enum within
video_core/texture.h.

We also don't need to all of these strings as translatable (only the
first string, as it's an English word).

Since c5d41fd8 callback parameters were
changed to use an s64 to represent late cycles instead of an int, so
this was causing a truncation warning to occur here. Changing it to s64
is sufficient to silence the warning.

These aren't used externally by anything, so they can be made private
data members.

Replaces header inclusions with forward declarations where applicable
and also removes unused headers within the cpp file. This reduces a few
more dependencies on core/memory.h

This is a hold over from the 3DS error codes in Citra.
