avcodec: add external enc libvvenc for H266/VVC

Browse Source 
Add external encoder VVenC for H266/VVC encoding.
Register new encoder libvvenc.
Add libvvenc to wrap the vvenc interface.
libvvenc implements encoder option: preset,qp,qpa,period,
passlogfile,stats,vvenc-params,level,tier.
Enable encoder by adding --enable-libvvenc in configure step.

@section libvvenc
VVenC H.266/VVC encoder wrapper.
This encoder requires the presence of the libvvenc headers and library
during configuration. You need to explicitly configure the build with
@option{--enable-libvvenc}.
The VVenC project website is at
@url{https://github.com/fraunhoferhhi/vvenc}.
@subsection Supported Pixel Formats
VVenC supports only 10-bit color spaces as input. But the internal (encoded)
bit depth can be set to 8-bit or 10-bit at runtime.
@subsection Options
@table @option
@item b
Sets target video bitrate.
@item g
Set the GOP size. Currently support for g=1 (Intra only) or default.
@item preset
Set the VVenC preset.
@item levelidc
Set level idc.
@item tier
Set vvc tier.
@item qp
Set constant quantization parameter.
@item subopt @var{boolean}
Set subjective (perceptually motivated) optimization. Default is 1 (on).
@item bitdepth8 @var{boolean}
Set 8bit coding mode instead of using 10bit. Default is 0 (off).
@item period
set (intra) refresh period in seconds.
@item vvenc-params
Set vvenc options using a list of @var{key}=@var{value} couples separated
by ":". See @command{vvencapp --fullhelp} or @command{vvencFFapp --fullhelp} for a list of options.
For example, the options might be provided as:
@example
intraperiod=64:decodingrefreshtype=idr:poc0idr=1:internalbitdepth=8
@end example
For example the encoding options might be provided with @option{-vvenc-params}:
@example
ffmpeg -i input -c:v libvvenc -b 1M -vvenc-params intraperiod=64:decodingrefreshtype=idr:poc0idr=1:internalbitdepth=8 output.mp4
@end example
@end table
