Fix T34993: "Jump to Next Keyframe" shortcut not related to the timeline viewable keyframes

Made the timeline option to only show keyframes from selected channels/data be a
per-scene setting instead of the per-timeline option it was previously. This makes
it easier for animators working on rigs with multiple bones (especially during the
polishing phase), since now the timeline and jump to keyframe operators use the same
setting to decide which subset of keyframes they need to consider.

By default, this option is enabled by default.

TODO: Extend this to the keyframe status shading on the active object name in the 3D view?
