This allows users to leverage the OpenH264 codec from Cisco to encode H.264 video content. It is significantly reduced in capability from alternatives, but it does the job. This also provides a framework for adding support for other H.264 software codecs provided through FFmpeg.

Description
This is split out of #8529 to provide only the commit that adds the wiring for the codec.
This also provides a framework for adding support for other H.264 software codecs provided through FFmpeg.
Motivation and Context
A number of distributions use OpenH264 distributed by Cisco to provide a fully licensed H.264 implementation (in particular, both Fedora Linux and openSUSE Linux do). However, OBS Studio cannot currently use it.
This change allows OBS Studio to use OpenH264 through FFmpeg if it's available.
How Has This Been Tested?
This was tested on Fedora Linux 38-40 with ffmpeg 6.0-6.1 and CentOS Stream 9 with ffmpeg 5.1.4 on x86_64 and AArch64.
