Add CSS filter support (#3923)
* Implement `filter` helper classes with all methods * Rename filter plugins/utilities, drop filter opacity, add drop shadow * Remove non-final default filter values * Working on default filter values, add basic JIT support * Working on blur values * New blur values (these are ~okay) * Match drop-shadow values to box-shadows by eye as best as possible * Update tests * Fix kitchen sink test * Add filter variants configuration * Move drop-shadow to end of filters list Co-Authored-By: Peter Neupauer <peter@neupauer.sk> * Add invert variants configuration * Add backdrop-filter utilities * Update tests * Transition filters by default * Alphabetize new config keys * Optimize filter plugins for JIT + add arbitrary value support Except for drop-shadow, will add that once we can think it through a bit.
