What is the need for making the changes to getBytesPerRow() and getBytesPerLayer()?

I might be missing something, but I don't see how it changes the use of these functions in the code in this PR.

If the change is required, neither of these functions are connected to MIP levels now, so the function documentation should be changed, at the very least.

I tried explaining it at the bottom of the PR message. When I originally transformed the code to be all in MVKDevice I came across these functions and it just bugged me that it would call getExtent3D 3 times and getBytesPerRow 2 times, when every caller of getBytesPerLayer would need the values themselves and could instead just pass them as a parameter. So I decided to refactor this a bit just to remove some wasted function calls.

Not entirely related to the current state of the PR, but it was relevant to the original change where I re-implemented the memory requirement functions in the MVKDevice object.
