Refactor Texture Swizzling

The API for texture swizzling is now more concrete and abstracted out from `GuestTexture`, this allows for neater usage in certain areas such as MaxwellDMA while having a `GuestTexture` wrapper as well allowing for neater usage in those cases. 

The code itself has also been cleaned up slightly with all usage of `u32`s being upgraded to `size_t` as this is simply more efficient due to the compiler not needing to emulate wraparound behavior for integer types smaller than the processor word size.
