Support interactive widgets in tooltips (#4596)
* Closes https://github.com/emilk/egui/issues/1010

### In short
You can now put interactive widgets, like buttons and hyperlinks, in an
tooltip using `on_hover_ui`. If you do, the tooltip will stay open as
long as the user hovers it.

There is a new demo for this in the egui demo app (egui.rs):


![interactive-tooltips](https://github.com/emilk/egui/assets/1148717/97335ba6-fa3e-40dd-9da0-1276a051dbf2)

### Design
Tooltips can now contain interactive widgets, such as buttons and links.
If they do, they will stay open when the user moves their pointer over
them.

Widgets that do not contain interactive widgets disappear as soon as you
no longer hover the underlying widget, just like before. This is so that
they won't annoy the user.

To ensure not all tooltips with text in them are considered interactive,
`selectable_labels` is `false` for tooltips contents by default. If you
want selectable text in tooltips, either change the `selectable_labels`
setting, or use `Label::selectable`.

```rs
ui.label("Hover me").on_hover_ui(|ui| {
    ui.style_mut().interaction.selectable_labels = true;
    ui.label("This text can be selected.");

    ui.add(egui::Label::new("This too.").selectable(true));
});
```

### Changes
* Layers in `Order::Tooltip` can now be interacted with

GUI implementation

This is the core library crate egui. It is fully platform independent without any backend. You give the egui library input each frame (mouse pos etc), and it outputs a triangle mesh for you to paint.
