Emil Ernerfeldt 41aad74552 Cross-widget text select (#3870) ...

* Closes https://github.com/emilk/egui/issues/3816


![cross-widget-text-selection](https://github.com/emilk/egui/assets/1148717/5582b9d2-8b04-47b7-9637-f48e44064a70)

Turn off with `style.interaction.multi_widget_text_select`.

There is an API for this in `LabelSelectionState`, but it's pretty
bare-bones.

This became really hairy implementation-wise, but it works decently
well.

# Limitations
* Drag-select to scroll doesn't work
* A selection disappears if you scroll past one of its end-points
* Only the text of labels and links are selectable
 
## TODO
* [x] An option to turn it off
* [x] An API for querying about the selected text, and to deselect it.
* [x] Scrolling past selection behaves weird
* [x] Shift-click to select a range
