693ec509d7 memory_manager: Eliminate variable shadowing 
Renames some variables to prevent ones in inner scopes from shadowing
outer-scoped variables.

The Copy* functions have no shadowing, but we rename them anyways to
remain consistent with the other functions.

34be867080 PageTable: move backing addresses to a children class as the CPU page table does not need them. 
This PR aims to reduce the memory usage in the CPU page table by moving
GPU specific parameters into a child class. This saves 1Gb of Memory for
most games.

542ab1b1b9 video_core/memory_manager: Mark IsBlockContinuous() as a const member function 
Corrects the typo in its name and marks the function as a const member
function, given it doesn't actually modify memory manager state.

cb867f250a video_core/memory_manager: Default the destructor within the cpp file 
Makes the class less surprising when it comes to forward declaring the
type, and also prevents inlining the destruction code of the class,
given it contains non-trivial types.

57744806c3 video_core/memory_manager: Remove superfluous const from function declarations 
These are able to be omitted from the declaration of functions, since
they don't do anything at the type system level. The definitions of the
functions can retain the use of const though, since they make the
variables immutable in the implementation of the function where they're
used.

69846b1557 video_core/memory_manager: Make Read() a const qualified member function

e36500c07f video_core/memory_manager: Make ReadBlock() a const qualifier 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.
