Auto merge of #34886 - jseyfried:improve_stmt_matchers, r=eddyb
macros: fix bug in `stmt` matchers
Today, `stmt` matchers stop too early when parsing expression statements that begin with non-braced macro invocations. For example,
```rust
fn main() {
macro_rules! m { ($s:stmt;) => { $s } }
id!(vec![].push(0););
//^ Before this PR, the `stmt` matcher only consumes "vec![]", so this is an error.
//| After this PR, the `stmt` matcher consumes "vec![].push(0)", so this compiles.
}
```
This change is backwards compatible due to the follow set for `stmt`.
