Clarify texture cache code. Previously, there were THREE sets of texture dimensions, and it was hard to tell which set was for what purpose.

Browse Source 
Now, there are two:
Real dimensions: Width and height of the original GameCube texture
Virtual dimensions: Width and height of the texture used by dolphin-emu's renderer
