This merges the `GRAPH_OT_keyframe_jump` operator into the more generic
`SCREEN_OT_keyframe_jump` operator. (the former introduced with #108549)
The functionality of both operators is retained by running
a `switch/case` based on the editor type.
Doing so, we can filter out the Dope Sheet as well which fixes#93944
The `GRAPH_OT_keyframe_jump` is preserved, but when it is called,
it generates a warning stating it should not be used anymore.
It then calls directly into the `SCREEN_OT_keyframe_jump` to
ensure functionality doesn't drift apart.
