The profiles need to be added to the list of usable profiles in
h264_options so they can be used on the command line.
Using the FF_PROFILE_ constants doesn't follow the pattern of using the
profile constants defined in this file, but I like your approach better. To
keep things consistent, either remove the constants in VT_H264Profile and
VT_HEVCProfile and replace them with global constants, or I can follow up
with a patch.

Thank you for your review, Kern.
I will remove VT_H264Profile and VT_HEVCProfile, replace with avctx->profile.
And submit a new patch of CBP/CHP after that.
