Capture/Replay: Add replay state validation. We can use this to validate traces that have slight differences when retracing. The valdation works by embedding the "expected" JSON into a string at the end of each captured frame. The replay also embeds a callback which fires right before the swap in the replay harness. The harness then gets the "actual" JSON and runs a comparison. On a mismatch it calls "diff" externally. Currently the diff call is hard-coded to work on Linux only. Note that when running validation it's important to replay on SwiftShader since that's what we use to retrace.
