Fix validation of PVRTC compressed texture sizes.

The PVRTC format, as pointed out by Le Hoang Quyen and Geoff Lang, uses 4x4 or 8x4 blocks, but due to sampling from adjacent blocks, requires a minimum size of 2x2 blocks per the OpenGL extension: https://www.khronos.org/registry/OpenGL/extensions/IMG/IMG_texture_compression_pvrtc.txt . Thanks to Quyen and Geoff for pointing out the intricacies. Add a helper function to formatutils.cpp which returns the minimum number of blocks (width and height) for a given compressed texture format, and incorporate this into the compressed texture size computation. This patch makes WebKit on ANGLE pass WebGL's PVRTC compressed texture test on iOS hardware.
