libcamera: formats: Add planeSize() helpers to PixelFormatInfo
Add two helpers functions to the PixelFormatInfo class to compute the
byte size of a given plane, taking the frame size, the stride, the
alignment constraints and the vertical subsampling into account.
Use the new functions through the code base to replace manual
implementations.
