Changes how context states are serialized during capture run. Now,
context states are serialized after each frame until the end frame
is reached, or context is destroyed.

Adds an api to the trace files to query serialization results of
multiple frames. Makes change to CaptureReplayTest to serialize
multiple frames then compares the serialization results with the ones
retrieved from said api.

Adds to capture replay the ability to produce working, compilable trace
files even when end frame is not reached.

Adds to the generated trace files config information and makes
CaptureReplayTest utilize said config information to reproduce the exact
environment of the captured application.
