Remove KeyframeList::addProperty()

https://bugs.webkit.org/show_bug.cgi?id=241805

Patch by Antoine Quint <graouts@apple.com> on 2022-06-21
Reviewed by Dean Jackson.

This method is not needed since KeyframeList::insert() already adds the properties
of the newly inserted keyframe to KeyframeList::m_properties.
