vaapi_encode: Add common options between all encoders

Browse Source 
The only common option here is low_power - it was previously supported
for H.264 only, that specific option is removed.

All encoders support the following options:
@itemize
@item
@option{low_power}
Some drivers/platforms offer a second encoder for some codecs intended to use
less power than the default encoder; setting this option will attempt to use
that encoder. Note that it may support a reduced feature set, so some other
options may not be available in this mode.

Each encoder also has its own specific options:
