avcodec: add API for automatic handling of icc profiles

Browse source 
This functionally already exists, but as pointed out in #9672 and #9673,
requiring users to manually include filters is clumsy, error-prone and
hard to use together with tools like ffplay.

To streamline ICC profile support, add a new AVCodecContext flag to
globally enable reading and writing ICC profiles, automatically, for all
appropriate media types.

Note that this commit only includes the new API. The implementation is
split off to separate commits for readability.
