Added support for Time Elapsed queries through the command buffer.

This CL adds support for Time Elapsed queries through the command
buffer.

Since it was easy to support, I have also added support
for getting the current TimeStamp through GetInteger64(),
GetInteger()...etc. Note that this is different from getting the
GPU timestamp using QueryCounter which is asynchronous.
