Revert of revert of time elapsed queries through command buffer.

Revert of revert of time elapsed queries through command buffer.

The original CL was thought to have caused a crash, but it was found to

Original issue's description:
> Added support for Time Elapsed queries through the command buffer.

> This CL adds support for Time Elapsed queries through the command

> Since it was easy to support, I have also added support

> GetInteger()...etc. Note that this is different from getting the
> GPU timestamp using QueryCounter which is asynchronous.
