Implements color matrix and transform modification support for Filterrific (#93867)

## About The Pull Request

Allows users to edit color matrix filters and layered filters'
transforms through Filterrific, which were the two last unsupported
filter fields. The menus are pretty minimal, but you shouldn't be
touching them if you don't know what you're doing anyways.
