* gh-154511: Consolidate IDLE's mouse wheel handling in util (GH-156974)
Move wheel_event there from idlelib.tree and add x11_buttons(widget) and
bind_wheel(widget, func), used by the editor, the tree and test_sidebar.
wheel_event now reads the direction from the event, not the platform.
Move its test from test_tree, and test the fix_ functions of util too.
(cherry picked from commit 57594aae5e)

Misc.tk_scaling is new in 3.16, and fix_scaling itself calls "tk
scaling" here.
