Sam Atkins 5b77346f53 LibGUI: Allow double-clicking PathBreadcrumbbar buttons to edit path
When viewing a deeply nested path, there may be very little of the
PathBreadcrumbbar itself visible to double-click on. This solves that
by allowing double-clicks on its segment buttons to behave the same.
(With the caveat that it first selects the double-clicked segment.)

In order to make this work, `on_double_click` now takes the modifiers
instead of the MouseEvent. In this case we don't use it so that's fine,
but maybe we should make all mouse callbacks consistently take the
MouseEvent& as a parameter.
