Rename CoglIndexArray to CoglIndexBuffer

Browse Source 
This is part of a broader cleanup of some of the experimental Cogl API.
One of the reasons for this particular rename is to switch away from
using the term "Array" which implies a regular, indexable layout which
isn't the case. We also want to strongly imply a relationship between
CoglBuffers and CoglIndexBuffers and be consistent with the
CoglAttributeBuffer and CoglPixelBuffer APIs.
