Add check-capture-replay flag

Add --check-capture-replay flag for dawn_end2end_tests.
When it's on it turns on capture the test body.

On Teardown it finish capturing and replay the capture.
For each Buffer and Texture readback expectations,
it get and map the replayed readback buffer by label
comparing the raw bytes to the
original readback buffer to see if it is an exact match.

Add a temp allowlist toggle enable_for_check_capture_replay at the
same time. Since many tests will fail checking capture_replay
at this time, instead of suppressing failure tests, we turn on
passing tests by specifying a
WebGPUBackend({"enable_for_check_capture_replay"}) config.

Locally we can run dawn_end2end_tests with --check-capture-replay
and --enable-toggles=enable_for_check_capture_replay at the same
time to turn on check capture replay.

Once implementation are more complete we can remove
enable_for_check_capture_replay.
