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.

numeric vars can only be unified with numerical types in deep reject
Don't consider numeric vars (int and float vars) to unify with non-numeric types during deep reject. This helps us reject incompatible impls sooner.
Closures always implement `FnOnce` in new solver
We should process `[closure]: FnOnce(Tys...) -> Ty` obligations *before* fallback and closure analysis. We can do this by taking advantage of the fact that `FnOnce` is always implemented by closures, even before we definitely know the closure kind.

Freshen normalizes-to hack goal RHS in the evaluate loop
Ensure that we repeatedly equate the unconstrained RHS of the normalizes-to hack goal with the *actual* RHS of the goal, even if the normalizes-to goal loops several times and thus we replace the unconstrained RHS var repeatedly.
Alternative to #109583.
Don't ICE on placeholder consts in deep reject
Since we canonicalize const params into placeholder consts, we need to be able to handle them during deep reject.

rustdoc: run more HIR validation to mirror rustc
# Explanation
While investigating these issues: https://github.com/rust-lang/rust/issues/107093, https://github.com/rust-lang/rust/issues/106079
I thought it maybe would be useful to test running `rustdoc` on all rust files under `tests/ui` grepping for files that causes any ICEs.
And these are the files I found would cause ICEs.
```
// These are handled by this fix.
tests/ui/late-bound-lifetimes/mismatched_arg_count.rs
tests/ui/associated-consts/issue-102335-const.rs
tests/ui/const-generics/generic_const_exprs/issue-102768.rs
tests/ui/const-generics/const-arg-type-arg-misordered.rs
tests/ui/generic-associated-types/parse/trait-path-type-error-once-implemented.rs
tests/ui/typeck/issue-88643.rs
tests/ui/typeck/issue-75889.rs
tests/ui/typeck/issue-83621-placeholder-static-in-extern.rs
// These are not they will still produce a ICE after this change
tests/ui/limits/issue-56762.rs
tests/ui/union/projection-as-union-type-error-2.rs
tests/ui/union/projection-as-union-type-error.rs
```
I reduces the issues handled by this PR down to the tests added in the PR. That includes the linked issues.
But the 3 files that are not handled I will leave for a future PR.
This PR adds the `type_collecting` step from `hir_analysis::check_crate` to the rustdoc typechecks.
It had the following comment on it.
```
// this ensures that later parts of type checking can assume that items
// have valid types and not error
```
Adding the check report the same errors as rustc does for these input.
And not ICE when the lint checker walks the HIR or when in the `rustdoc::clean` pass.
This PR updates the expected errors of some existing rustdoc-ui tests (some now report less errors).
These new reported errors does mirror the errors reported by rustc.
# Performance
It does more checking so it will probably regress. We should run ``@bors` try `@rust-timer` queue` and see.
# Discussion
Maybe instead of calling a subset of the checks in `hir_analysis::check_crate` and having comments that say they should be kept in sync. We could instead call `check_crate` directly and pass in some flag. Maybe `check_toplevel_signatures_only` or something like that. That flag would have to skip most of the checks in that function tough.
apparently I missed some tests in the last commit. Rather than having
dozens of tests use the long version, use the short version in
`run-make` and the long version in `run-make-fulldeps` (which is now
only three tests)
