avfilter/vf_libplacebo: update for new tone mapping API
Upstream gained a new tone-mapping API, which we never switched to. We don't need a version bump for this because it was included as part of the v4.192 release we currently already depend on. Some of the old options can be moderately approximated with the new API, but specifically "desaturation_base" and "max_boost" cannot. Remove these entirely, rather than deprecating them. They have actually been non-functional for a while as a result of the upstream deprecation. Signed-off-by: Niklas Haas <git@haasn.dev>
