Deprecate EmbedButtonEditorAccessCheck in favor of a generic access check for "does a filter format or editor have a filter plugin enabled"

Discovered while testing 📌 Add CKEditor 5 compatibility and keep supporting CKEditor 4 RTBC that our current access check handler might not be sustainable and we should rather do what core's media module does and checks if the filter format has the desired format plugin enabled, rather than checking the editor having the button enabled. It provides a more reliable check.
