Vizier: Add defaults for > 1080P

Vizier: Add defaults for > 1080P

Previous code did not have sensible defaults for larger image formats.

Added defaults for Vizier RD parameters for sizes > 1080P and changed
the first pass parameters for large formats to use the 1080P values.
No supplied value  for rd_mult_q_sq_key_high_qp case yet so set to
old hard wired default value.

If the Vizier parameters were enabled the lack of sensible defaults
caused a large regression for 2K clips in one of our test sets.
