Remove GL query processing from DrawElements/DrawArrays.
Remove GL query processing from DrawElements/DrawArrays.

Polling GL queries is taking ~7us each time on Android.  Processing
queries from ::DrawElements & ::DrawArrays may not be a good idea as
50 to 100 draw calls per-frame with GPU rendering is common
i.e. 350~700us, and more so as we aim for handling higher draw call
counts in the future.

Pending queries are still polled in the following cases:
 - After glFlush().
 - After glFinish().
 - After processing any GpuCommandBufferStub  IPC message.
 - As delayed work, at up to 1000Hz.
