Add auto focus timeline and bezier scale on animation editor

Add a button at the bottom of the animation editor that change the zoom based on the animation length and the bezier scale based on the values and handles of the displayed tracks. The icon and the tooltip of the button change depending if the bezier editor is displayed or not.

Some refactor was made in animation_track_editor.cpp to remove code duplication with the visibility check of the tracks.

This should help with the issue #85826
