This PR begins the process of breaking up the `style_helpers!` macro
into smaller macros that can be used to generate methods for a related
subset of styles.
The style method macros also now accept an optional `visibility`
parameter to control the visibility of the generated methods. This
allows for adding these methods to a struct instead of a just a trait.
For example, to expose just the padding styles on a `Facepile` we can do
this:
```rs
impl Facepile {
fn style(&mut self) -> &mut StyleRefinement {
self.base.style()
}
gpui::padding_style_methods!({
visibility: pub
});
}
```
