Resolve function lifetime elision on the AST

~Based on https://github.com/rust-lang/rust/pull/97720~

Lifetime elision for functions is purely syntactic in nature, so can be resolved on the AST.
This PR replicates the elision logic and diagnostics on the AST, and replaces HIR-based resolution by a `delay_span_bug`.

This refactor allows for more consistent diagnostics, which don't have to guess the original code from HIR.

e5a86d7358 Rollup merge of #98705 - WaffleLapkin:closure_binder, r=cjgillot 
Implement `for<>` lifetime binder for closures

This PR implements RFC 3216 ([TI](https://github.com/rust-lang/rust/issues/97362)) and allows code like the following:

```rust
let _f = for<'a, 'b> |a: &'a A, b: &'b B| -> &'b C { b.c(a) };
//       ^^^^^^^^^^^--- new!
```

38b72154de Auto merge of #98637 - cjgillot:bare-trait-anon-lt, r=petrochenkov 
Create fresh lifetime parameters for bare fn trait too

The current code fails to account for the equivalence between `dyn FnMut(&mut u8)` and bare `FnMut(&mut u8)`, and treated them differently.

This PR introduces a special case for `Fn` traits, which are always fully resolved.

Fixes #98616
Fixes #98726
This will require a beta-backport, as beta contains that bug.
