CKEditorComponent - use new angular standards (standalone, zoneless)

[joergbaier]

This is a suggestion to adopt the newer angular patterns, the ones I am aware of are:

Standalone Components
This should be fairly simple.
Minimum Angular version 14

Zoneless
As a first step, I would look into supporting OnPush change detection.
Followed by converting Input/Output/etc to be signal based. (Minimum Angular version 17.2)
Also note that NgZone.run and NgZone.runOutsideAngular are compatible with Zoneless (experimental in 18)

It would be cool to start migrating slowly to signals.
