Rollup merge of #62928 - Centril:recover-parens-around-for-head, r=estebank 
Syntax: Recover on `for ( $pat in $expr ) $block`

Fixes #62724 by adding some recovery:

```
error: unexpected closing `)`
  --> $DIR/recover-for-loop-parens-around-head.rs:10:23
   |
LL |     for ( elem in vec ) {
   |         --------------^
   |         |
   |         opening `(`
   |         help: remove parenthesis in `for` loop: `elem in vec`
```

Rollup merge of #62668 - goodmanjonathan:fix-62660, r=estebank 
Fix #62660

If the explicitly given type of a `self` parameter fails to parse correctly, we need to propagate the error rather than dropping it and causing an ICE.

Fixes #62660.

Rollup merge of #62292 - Centril:split-async-closures, r=cramertj 
Move `async || ...` closures into `#![feature(async_closure)]`

The `async || expr` syntax is moved out from `#![feature(async_await)]` into its own gate `#![feature(async_closure)]`.

New tracking issue: https://github.com/rust-lang/rust/issues/62290

Closes https://github.com/rust-lang/rust/issues/62214.

Rollup merge of #62258 - petrochenkov:idclean, r=Centril 
syntax: Unsupport `foo! bar { ... }` macros in the parser

Their support in expansion was removed in https://github.com/rust-lang/rust/pull/61606.

Also un-reserve `macro_rules` as a macro name, there's no ambiguity between `macro_rules` definitions and macro calls (it also wasn't reserved correctly).
