[test] add flash scrambling/ECC smoketest

This adds a simple flash scrambling/ECC smoketest to DV to test the `gen-flash-img.py` can properly prepare a flash image for backdoor loading in flash in DV. This test is also added to the list of tests run in pre-submit CI. Signed-off-by: Timothy Trippel <[email protected]>
