Refactor brushable component

[TheDeathlyCow]

Another refactor aimed to better use cardinal components, this time for the brushable component.

Also adds new functionality in the form of tag-driven brushing.

• Items that use the tag #c:tools/brush are now acceptable for brushing
• Animals with the tag #frostiful:is_brushable can be brushed
• Animals with the tag #frostiful:brushing/drops_polar_bear_fur will drop polar bear fur tufts when brushed
• Animals with the tag #frostiful:brushing/drops_wolf_fur will drop wolf fur tufts when brushed
• Animals with the tag #frostiful:brushing/drops_ocelot_fur will drop ocelot fur tufts when brushed
• If an animal is brushable but doesn't also have an associated fur tuft, a warning will be displayed in the console
