Badly-behaved consumers of DrawTargetRecording can trigger recording of draw calls that will fail to allocate required draw targets when the recording is replayed. This patch tries to guard against this by detecting these situations at record-time rather than crashing at replay-time. When such a situation is detected, it will crash (for content processes, to catch such scenarios) or gracefully fail (for other processes).
