va: h264dec: Allow "extended" profile decoding

Extended is identical to main but allows for FMO/ASO features to be
used, and prevent using CABAC. Using similar logic to "baseline",
assume that if we support main, we can also do extended.

This fixes the following fluster vectors, which otherwise would fail
when trying to link the parsebin pad.

  - BA3_SVA_C
  - MR6_BT_B
  - MR7_BT_B
  - MR8_BT_B
