avfilter/vf_libplacebo: update metadata stripping logic

Browse Source 
Switches to av_frame_side_data_remove_by_props(), covering a number of
cases that we previously ignored. Additionally, stop stripping metadata
when merely changing colorspace or color range, since these do not
affect the actual color volume of the image data, only the encoding.
