MVKImage: Use the plane's MTLPixelFormat to calculate memory sizes.

We really don't want to use the `VkFormat` for the whole image. That has
a block size set on it, which causes the size to be reduced by a factor
of two or even four, in the case of a 420 format whose pitch exceeds the
required alignment. If instead we use the plane `MTLPixelFormat`, we can
sidestep that.
