Capture/Replay: Reset buffers on replay loop

Browse Source 
This CL adds infrastructure for tracking whether resources need to be
reset when looping back to the beginning of the frame sequence.

A new function is generated on the last frame: ResetContext*Replay().
It will contain calls to gen, delete, and restore contents of
resources. This CL only supports Buffer resets.
