media: v4l2-ctrls: set AV1 sequence flags for testing

Initialize additional AV1 sequence parameters in std_init_compound()
to make the default AV1 sequence control compatible with compliance
and userspace testing tools.

Specifically, set:
 - enable both SUBSAMPLING_X and SUBSAMPLING_Y flags

These defaults help ensure that V4L2_CID_AV1_SEQUENCE behaves
consistently during validation and v4l2-compliance tests.
