fftools/ffmpeg_sched: add a function to remove a filtergraph from the
scheduler
For the purpose of merging streams in a stream group, a filtergraph can't be
created once we know it will be used. Therefore, allow filtergraphs to be
removed from the scheduler after being added.

fftools/ffmpeg_mux_init: allow creating streams from filtergraphs created
out of stream groups
Several formats are being designed where more than one independent video or
audio stream within a container are part of what should be a single combined
output. This is the case for HEIF (Defining a grid where the decoded output
of several separate video streams are to be placed to generate a single
output
image) and IAMF (Defining audio streams where channels are present in
separate
coded stream).
AVStreamGroup was designed and implemented in libavformat to convey this
information, but the actual merging is left to the caller.
This change allows the FFmpeg CLI to take said information, parse it, and
create filtergraphs to merge the streams, making the combined output be
usable
automatically further in the process.

fftools: pass global side data through using a separate array
This keeps global and per frame side data clearly separated, and actually
propagates the former as it comes out from the buffersink filter.

fftools/ffmpeg_filter: fix passing certain parameters to inputs bound to a
filtergraph output
Certain parameters, like calculated framerate, are unavailable when
connecting
the output of a filtergraph to the input of another.
This fixes command lines like
ffmpeg -lavfi "testsrc=rate=1:duration=1[out0]" -filter_complex
"[out0]null[out1]" -map [out1] -y out.png
