core/memory: Minor simplifications to page table management

gl_state: Rework to enable individual applies

gl_shader_disk_cache: Use Zstandard for compression

kernel/{server_port, server_session}: Return pairs instead of tuples from pair creation functions

core/memory: Remove unused enum constants

memory_manager: Improved implementation of read/write/copy block.

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.

Implement SyncPoint Register in the GPU.

video_core/macro_interpreter: Simplify GetRegister()

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)
