Camera VTS: Test only CROPPED_RAW use case for RAW_SENSOR streams

There are no mandatory stream combinations for RAW_SENSOR streams that
do not involve the CROPPED_RAW stream use case. So we don't need to test
stream non CROPPED_RAW stream use cases with the RAW_SENSOR format,
since we don't have a definite answer to whether they will be supported or not.

Bug: 317773720

Test: Camera VTS on cf
Test: Vendor testing
