Refactor AST trait bound modifiers
Instead of having two types to represent trait bound modifiers in the parser / the AST (`parser::ty::BoundModifiers` & `ast::TraitBoundModifier`), only to map one to the other later, just use `parser::ty::BoundModifiers` (moved & renamed to `ast::TraitBoundModifiers`).
The struct type is more extensible and easier to deal with (see [here](https://github.com/rust-lang/rust/pull/119099/files#r1430749981) and [here](https://github.com/rust-lang/rust/pull/119099/files#r1430752116) for context) since it more closely models what it represents: A compound of two kinds of modifiers, constness and polarity. Modeling this as an enum (the now removed `ast::TraitBoundModifier`) meant one had to add a new variant per *combination* of modifier kind, which simply isn't scalable and which lead to a lot of explicit non-DRY matches.
NB: `hir::TraitBoundModifier` being an enum is fine since HIR doesn't need to worry representing invalid modifier kind combinations as those get rejected during AST validation thereby immensely cutting down the number of possibilities.
On LLVM 18 we get slightly different arguments here, so it's easier to
just regex those away. The important details are all still asserted as I
understand things.
Fixes#119193.

Fix name error in aarch64_apple_watchos tier 3 target
fix llvm_target wrong name `aarch-apple-watchos` to `aarch64-apple-watchos`, sorry for my mistake.

Simple modification of `non_lifetime_binders`'s diagnostic information to adapt to type binders
fixes#119067
Replace diagnostic information "lifetime bounds cannot be used in this context" to "bounds cannot be used in this context".
```rust
#![allow(incomplete_features)]
#![feature(non_lifetime_binders)]
trait Trait {}
trait Trait2
where for <T: Trait> ():{}
//~^ ERROR bounds cannot be used in this context
```
- Make temporaries in if-let guards be the same variable in MIR when
the guard is duplicated due to or-patterns.
- Change the "destruction scope" for match arms to be the arm scope rather
than the arm body scope.
- Add tests.
Give `VariantData::Struct` named fields, to clairfy `recovered`.
Implements https://github.com/rust-lang/rust/pull/119121#discussion_r1431467066. Supersedes #119121
This way, it's clear what the bool fields means, instead of having to find where it's generated. Changes both ast and hir.
