Issue description

There are several signals in AnimationBezierTrackEdit that remain unused, namely timeline_changed, remove_request, close_request, move_selection_begin, move_selection, move_selection_commit, and move_selection_cancel.

Defined within this block:

godot/editor/animation_bezier_editor.cpp

Lines 1659 to 1669 in 4df80b0

	ADD_SIGNAL(MethodInfo("timeline_changed", PropertyInfo(Variant::FLOAT, "position"), PropertyInfo(Variant::BOOL, "drag")));
	ADD_SIGNAL(MethodInfo("remove_request", PropertyInfo(Variant::INT, "track")));
	ADD_SIGNAL(MethodInfo("insert_key", PropertyInfo(Variant::FLOAT, "offset")));
	ADD_SIGNAL(MethodInfo("select_key", PropertyInfo(Variant::INT, "index"), PropertyInfo(Variant::BOOL, "single"), PropertyInfo(Variant::INT, "track")));
	ADD_SIGNAL(MethodInfo("clear_selection"));
	ADD_SIGNAL(MethodInfo("close_request"));
	ADD_SIGNAL(MethodInfo("move_selection_begin"));
	ADD_SIGNAL(MethodInfo("move_selection", PropertyInfo(Variant::FLOAT, "offset")));
	ADD_SIGNAL(MethodInfo("move_selection_commit"));
	ADD_SIGNAL(MethodInfo("move_selection_cancel"));

Possibly related to issues #31783 and #31924 since the addition of those signals predates those opened issues.

I might have forget to remove them. I think they are no longer used after the refactoring at #64647, but I haven't checked what is no longer needed.
