Differences to v0:
1. side data set structure moved to public AVCodecContext itself
2. set extension helper renamed to av_extend_side_data_set
3. avutil/frame.c cleanup patch removed as it was applied to master

This patch set I've now been working for a while since I felt like it was weird
we couldn't pass through information such as static HDR metadata to encoders
from decoded input. This initial version adds the necessary framework, as well
as adds static HDR metadata support for libsvtav1, libx264 as well as libx265
wrappers.

An alternative to this would be to make encoders only properly initialize when
they receive the first AVFrame, but that seems to be a bigger, nastier change
than introducing an AVFrameSideDataSet in avctx as everything seems to
presume that extradata etc are available after opening the encoder.
