Support extend and extend range channel selection. Some channeltype don't have active channel and they don't support `extend range`. This is done in `animchannel_has_active_of_type`. Add switch case for new GPv3 channels in above `ANIM_is_active_channel` to detect active channels and support `extend range` Part of #110056 Pull Request: https://projects.blender.org/blender/blender/pulls/110791
