video/filter: remove vf_match_csp()

This function improves automatic filter insertion, but this really
should be done by the generic filter code. Remove vf_match_csp() and all
code using it as preparation for that.

This commit temporarily makes handling of filter insertion worse for
now, but it will be fixed with the following commits.
