Provide info about default qualitiy for each codec

Summary of the bug:
The default value for option -q is missing, at least for encoder=libx264.
How to reproduce:
- search on https://ffmpeg.org/ffmpeg-codecs.html
- additionally try:
% ffmpeg -h encoder=libx264 ffmpeg version 4.1.3 built on gcc 6.3.0 (Debian 6.3.0-18+deb9u1) 20170516
From the output of using this encoder, I can see, it seems to be 28.0, but this is nowhere documented.
IMHO on https://ffmpeg.org/ffmpeg-codecs.html it should be possible to easily find for each codec:
- the default quality
- which option to use to change it (here -q)
ffmpeg -h encoder=blafoo should give this info.
