mesa: verify MaxVertexAttribStride for GLES 3.1

The OpenGL 3.1 specification, table Table 20.41 ("Implementation
Dependent Values"), defines the minimum-maximum value for
MAX_VERTEX_ATTRIB_STRIDE to be 2048.

So we shouldn't enable OpenGL ES 3.1 on implementations where this
isn't the case. Let's add a check for this
