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.
