e457001dce General: Make use of std::nullopt where applicable 
Allows some implementations to avoid completely zeroing out the internal
buffer of the optional, and instead only set the validity byte within
the structure.

This also makes it consistent how we return empty optionals.

9a974b8cb9 memory_manager: Mark IsGranularRange() as a const member function 
This doesn't modify internal member state, so it can be marked as const.

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.

4e57de9e0b Prevent merging of device mapped memory blocks. 
This sets the DeviceMapped attribute for GPU-mapped memory blocks,
and prevents merging device mapped blocks. This prevents memory
mapped from the gpu from having its backing address changed by
block coalesce.

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.

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.

We don't need to keep calling the same function over and over again in a

keep a reference to the looked up location and do all the checking and
assignments based off it instead.
