libs: encoder: vp9: Add allowed_profiles.

We need the allowed_profiles to store the allowed profiles in down
stream's caps.
Command line like:
  vaapivp9enc ! capsfilter caps=video/x-vp9,profile="{ (string)1, \
    (string)3 }"
We need to store GST_VAAPI_PROFILE_VP9_1 and GST_VAAPI_PROFILE_VP9_3
in this list.
