Fix for the remaining vertex array issues

Fixes all failures in dEQP.functional.vertex_arrays.* In OpenGL ES 3.0, vertex attributes streams can be of a different type from the vertex attribute in the shader. For this reason, some conversion may be required. This cl solves this issue by: 1) Sending the information about the vertex attribute's type in the shader to the vertex routine. 2) Handling this information by adding conversion where appropriate.
