Fixes some Filteriffic issues and implements colorspace/blend mode controls (#93145)

## About The Pull Request

- Fixes filteriffic erroring out when trying to edit a filter
- Implements plugs for color/transform matrix editing rather than just
displaying an error
- Fixes bloom threshold displaying as a float rather than a color due to
an overlap with rays filter
- Displace filter flags can now be controlled
- Color matrix filter now allows the user to change the colorspace (not
really that useful considering you still can't edit the matrix)
- Layering filter now allows the user to control its blending mode
(actually useful this time)

## Changelog
🆑
fix: Fixed filteriffic runtiming when editing filters, and claiming that
bloom threshold is a number
admin: Filteriffic got a few new options (you should still avoid using
it)
