Rollup merge of #121179 - RalfJung:zst-mutable-refs, r=oli-obk 
allow mutable references in const values when they point to no memory

Fixes https://github.com/rust-lang/rust/issues/120450

The second commit is just some drive-by test suite cleanup.

73b38c661d Do not allocate a second "background" alloc id for the main allocation of a static. 
Instead we re-use the static's alloc id within the interpreter for its initializer to refer to the `Allocation` that only exists within the interpreter.

Rollup merge of #120950 - compiler-errors:miri-async-closurs, r=RalfJung,oli-obk 
Fix async closures in CTFE

First commit renames `is_coroutine_or_closure` into `is_closure_like`, because `is_coroutine_or_closure_or_coroutine_closure` seems confusing and long.

Second commit fixes some forgotten cases where we want to handle `TyKind::CoroutineClosure` the same as closures and coroutines.

The test exercises the change to `ValidityVisitor::aggregate_field_path_elem` which is the source of #120946, but not the change to `UsedParamsNeedSubstVisitor`, though I feel like it's not that big of a deal. Let me know if you'd like for me to look into constructing a test for the latter, though I have no idea what it'd look like (we can't assert against `TooGeneric` anywhere?).

Fixes #120946

5fa69deb00 fix cycle error when a static and a promoted are mutually recursive 
This also now allows promoteds everywhere to point to 'extern static', because why not?
We still check that constants cannot transitively reach 'extern static' through references.
(We allow it through raw pointers.)

Rollup merge of #120683 - RalfJung:symbolic-alignment-ice, r=oli-obk 
miri: fix ICE with symbolic alignment check on extern static

Fixes https://github.com/rust-lang/miri/issues/3288. Also fixes [this example](https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=38ee338ff10726be72bdd6efa3386763).

This could almost be a Miri PR, except for that typo fix in the validator. I started this as a rustc patch since I thought I need rustc changes, and now it'd be too annoying to turn this into a Miri PR...

4abb455529 Update ty::VariantDef to use IndexVec<FieldIdx, FieldDef> 
And while doing the updates for that, also uses `FieldIdx` in `ProjectionKind::Field` and `TypeckResults::field_indices`.

There's more places that could use it (like `rustc_const_eval` and `LayoutS`), but I tried to keep this PR from exploding to *even more* places.
