Implemented GPU Timer Disjoint Value checking on the GLES2 Client.

Now that the GLES2 Decoder supports updating a disjoint value through
asynchronous shared memory, the client side can now check that value
and update the disjoint state. As long as the server side sets the
disjoint state at the right moment with respect to query availabilities,
the client will always be able to tell if queries were valid or not.
