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`
```

The last 2 commits are drive-by cleanups.

Allow attributes in formal function parameters

Implements https://github.com/rust-lang/rust/issues/60406.

This is my first contribution to the compiler and since this is a large and complex project, I am not fully aware of the consequences of the changes I have made.

**TODO**

- [x] Forbid some built-in attributes.
- [x] Expand cfg/cfg_attr

976541884f Tweak self arg not as first argument of a method diagnostic 
Mention that `self` is only valid on "associated functions"
```
error: unexpected `self` argument in function

```

When it is a method, mention it must be first
```

d3fff6cda7 move some functions from parser.rs to diagostics.rs 
parser.rs is too big. Some functions only for error reporting and error
recovery are being moved to diagostics.rs.
