 Split the codec option off from #22910 since they technically are two
 separate things.  Relevant details from the original ticket are as
 follows:

 Having massive "foot + gun" options in general is bad practice.

 The extra codecs will expose ffmpeg to the browser container, which is a
 concrete increase in attack surface for questionable gain (gstreamer is
 never allowed).

 It looks like the browser people sort of considered the ffmpeg situation
 at #18946, and I initially added the pref in #20806.  Really what should
 happen is that Tor Browser should bundle their own copy if it's that
 critical to functionality instead of pulling in one of 7 different .so
 files via dlopen (`dom/media/platforms/ffmpeg/FFmpegRuntimeLinker.cpp`).
