ES31: Refactor syncState in VertexArrayGL This patch intends to solve several design issues by refactoring the process of syncState in VertexArrayGL before implementing ES3.1 feature Vertex Attrib Binding on the OpenGL back-end. 1. Use nullptr as the flag of using client memory pointer 2. Simplify comparisons in updateAttribPointer. 3. Put all code related to mFunctions->vertexAttrib*Pointer() into an individual function 4. Remove redundant mStateManager->bindVertexArray() in all update* functioins and only call it once in syncState().
