vaapiencode: enhance how the profile is defined

Browse source 
This code doesn't define the profile used by the internal encoder, but
it used to "predict" which is going to be used and to get the caps
restrictions.

Before the profile was predicted by checking the donwstream caps, but
sometimes they are not defined, setting an unknown profile. In order
to enhances this situation, the encoder asks to internal encoder if it
has one. If so, it is used.

To ask the internal encoder's profile a new accessor function was
added: gst_vaapi_encoder_get_profile()
