Many widgets can be rendered without changing their state.
This commit implements The `Widget` trait for references to
widgets and changes their implementations to be immutable.
This allows us to render widgets without consuming them by passing a ref
to the widget when calling `Frame::render_widget()`.
```rust
// this might be stored in a struct
let paragraph = Paragraph::new("Hello world!");
let [left, right] = area.split(&Layout::horizontal([20, 20]));
frame.render_widget(¶graph, left);
frame.render_widget(¶graph, right); // we can reuse the widget
```
Implemented for all widgets except BarChart (which has an implementation
that modifies the internal state and requires a rewrite to fix.
Other widgets will be implemented in follow up commits.
