  Move Buffer from VertexBinding to VertexArray
  
  In later CL we will not taking shared context lock for certain
  VertexArray API calls. VertexArray itself is per context, so this sounds
  reasonable to do. The main challenge here is a lot of VertexArray
  function end up accessing gl::Buffer object, which could be modified by
  other shared contexts. In order to safely not taking the shared context
  lock, we need to separate out Buffer object out of VertexArray itself so
  that these lockless APIs will take VertexArray that does not have access
  to buffer.
  
  In this CL, VertexArray is split into two classes: VertexArrayPrivate is
  everything in VertexArray except buffers. VertexArray is a subclass of
  VertexArrayPrivate and owns all the buffers. Buffer is removed from
  gl::VertexBinding class. In order to let back end access to buffers,
  VertexArrayImpl holds a weak reference to
  VertexArray::mVertexArrayBuffers (which is a vector of buffers).
  Further, VertexArrayBufferBindingMask mBufferBindingMask is moved from
  VertexArrayState into VertexArray class well, since it tracks which
  index has a non-null buffer. The bulk of change are due to the
  VertexARrayImpl constructor change, since it now takes
  vertexArrayBuffers argument. Other bulk of changes are due to
  VertexBinding no long has the buffer, but you need to get it directly
  from VertexArray or VertexArrayImpl.
  
  This CL also reverts some of the change in crrev.com/c/6758215 that
  mVertexBindings no longer contains kElementArrayBufferIndex.
