Improve annotation of AST types for codegen.
Currently:
```rs
#[visited_node(
scope(ScopeFlags::empty()),
enter_scope_before(cases),
)]
pub struct SwitchStatement<'a> {
pub span: Span,
pub discriminant: Expression<'a>,
pub cases: Vec<'a, SwitchCase<'a>>,
pub scope_id: Cell<Option<ScopeId>>,
}
```
After this PR:
```rs
#[visited_node(scope(ScopeFlags::empty()))]
pub struct SwitchStatement<'a> {
pub span: Span,
pub discriminant: Expression<'a>,
#[scope(enter_before)]
pub cases: Vec<'a, SwitchCase<'a>>,
pub scope_id: Cell<Option<ScopeId>>,
}
```
I think this is easier to read.
In order to enable use of `#[scope]` attr, this introduces a dummy `VisitedNode` derive macro. Like the `visited_node` macro, `VisitedNode` derive macro is designed to do very minimal work and have no heavy dependencies, so it should be almost 0 cost in terms of compile time.
