overlookmotel fcd21a6a75 refactor(traverse): indicate scope entry point with scope(enter_before) attr (#3882)
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.
