ARMv6K Horizon OS has_thread_local support
cc. ```@ian-h-chamberlain```
cc. ```@AzureMarker```
Being an ARM target, it has always had built-in support for `#[thread_local]`. This PR comes in just now because we were testing `std::thread` support with `thread_local_dtor`s. This will hopefully be the last PR for the target specification, unless anymore features will be needed as time goes on.
interpret: with enforce_number_validity, ensure integers are truly Scalar::Int (i.e., no pointers)
This is required for https://github.com/rust-lang/miri/pull/2040

Skip pointing out ambiguous impls in alloc/std crates too in inference errors
This generalizes the logic in `annotate_source_of_ambiguity` to skip printing ambiguity errors traits in `alloc` and `std` as well, not just `core`.
While this does spot-fix the issue mentioned below, it would be nicer to generalize this logic, for example to detect when the trait predicate's `self_ty` has any numerical inference variables. Is it worthwhile to scrap this solution for one like that?

Remove `Session::one_time_diagnostic`
This is untracked mutable state, which modified the behaviour of queries.
It was used for 2 things: some full-blown errors, but mostly for lint declaration notes ("the lint level is defined here" notes).
It is replaced by the diagnostic deduplication infra which already exists in the diagnostic emitter.
A new diagnostic level `OnceNote` is introduced specifically for lint notes, to deduplicate subdiagnostics.
As a drive-by, diagnostic emission takes a `&mut` to allow dropping the `SubDiagnostic`s.
incr. comp.: Let compiler retry finalizing session directory a few times.
In my local testing this fixed issue https://github.com/rust-lang/rust/issues/86929. I wasn't able to come up with a regression test for it though.
Swap DtorckConstraint to DropckConstraint
This change was made as per suspicion that this struct was never renamed after consistent use of DropCk.
This also clarifies the meaning behind the name of this structure.
