libhb: Add filter preset/tune lookup and setting validation for more filter types

All filters except for crop_scale now have preset/tune support and basic
validation.

This code could also be used by the other frontends to simplify some things.
For example, it can be used to query libhb for a list of available presets
and tunes for each filter.
