fftools/graphprint: Add execution graph printing

Browse source 
The key benefits are:

- Different to other graph printing methods, this is outputting:
  - all graphs with runtime state
    (including auto-inserted filters)
  - each graph with its inputs and outputs
  - all filters with their in- and output pads
  - all connections between all input- and output pads
  - for each connection:
    - the runtime-negotiated format and media type
    - the hw context
    - if video hw context, both: hw pixfmt + sw pixfmt
- Output can either be printed to stdout or written to specified file
- Output is machine-readable
- Use the same output implementation as ffprobe, supporting multiple
  formats
