cogl: Adds experimental CoglVertexArray type This adds a new CoglVertexArray object which is a subclass of CoglBuffer used to hold vertex attributes. A later commit will add a CoglVertexAttribute API which will be used to describe the attributes inside a CoglVertexArray.

Rename CoglVertexArray to CoglAttributeBuffer 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 have a strongly implied relationship between CoglAttributes and CoglAttributeBuffers.

vertex-array: Adds data arg for _vertex_array_new() This adds an optional data argument for cogl_vertex_array_new() since it seems that mostly every case where we use this API we follow up with a cogl_buffer_set_data() matching the size of the new array. This simplifies all those cases and whenever we want to delay uploading of data then NULL can simply be passed.
