avfilter/avfiltergraph: Avoid allocation for AVFilterGraphInternal

Browse Source 
To do this, allocate AVFilterGraphInternal jointly with AVFilterGraph
and rename it to FFFilterGraph in the process (similarly to
AVStream/FFStream).
The AVFilterGraphInternal* will be removed on the next major version
bump.
