This PR removes the `full` style method and replaces it with
`size_full`, as the two do the same thing.

This is the generated code for `size_full`:

```rs
#[doc = "Sets the width and height of the element.\n\n100%"]
fn size_full(mut self) -> Self {
    let style = self.style();
    style.size.width = Some((gpui::relative(1.)).into());
    style.size.height = Some((gpui::relative(1.)).into());
    self
}
```
