lavfi: add ff_detect_color_primaries helper
Related to #9673, this helper exists to facilitate "guessing" the right
primary tags from a given set of raw primary coefficients.
The cutoff value of 0.001 was chosen by experimentation. The smallest
"false positive" delta observed in practice was 0.023329, while the
largest "false negative" delta was 0.00016. So, a value of 0.001 sits
comfortably in the middle.
