Since we don't inline for the JSON output, the impl blocks from private modules are not present when we generate the output. To go around this limitation, in case the impl block doesn't have `#[doc(hidden)]` and is implementing a public item, we don't strip it.

Auto merge of #2631 - RalfJung:futex-wait-no-isolate, r=RalfJung
Support timeouts with monotonic clocks even when isolation is enabled
With the deterministic monotonic clock support we now have, we can allow some synchronization primitives with timeouts even under isolation:
- Linux futex waiting (when set to the monotonic clock)
- pthread_cond_timedwait (when set to the monotonic clock)
- Windows WaitOnAddress
Unfortunately none of these exist on macOS -- the standard library always uses the system clock for timeouts on macOS, so that will still require `-Zmiri-disable-isolation`.

privacy: Rename "accessibility levels" to "effective visibilities"
And a couple of other naming and comment tweaks.
Related to https://github.com/rust-lang/rust/issues/48054
For `enum Level` I initially used naming `enum EffectiveVisibilityLevel`, but it was too long and inconvenient because it's used pretty often.
So I shortened it to just `Level`, if it needs to be used from some context where this name would be ambiguous, then it can be imported with renaming like `use rustc_middle::privacy::Level as EffVisLevel` or something.

poll_fn and Unpin: fix pinning
See [IRLO](https://internals.rust-lang.org/t/surprising-soundness-trouble-around-pollfn/17484) for details: currently `poll_fn` is very subtle to use, since it does not pin the closure, so creating a `Pin::get_unchcked(&mut capture)` inside the closure is unsound. This leads to actual miscompilations with `futures::join!`.
IMO the proper fix is to pin the closure when the future is pinned, which is achieved by changing the `Unpin` implementation. This is a breaking change though. 1.64.0 was *just* released, so maybe this is still okay?
The alternative would be to add some strong comments to the docs saying that closure captures are *not pinned* and doing `Pin::get_unchecked` on them is unsound.

Based on code by `@DrMeepster.` However I adjusted `WakeByAddressSingle`: I don't think the futex value is compared *again* after the thread is woken up. I see nothing in the Windows docs indicating such a comparison, and the Linux futex does not behave like that either. So we only check the value before sleeping, same as on Linux.

Fix line numbers for MIR inlined code
`should_collapse_debuginfo` detects if the specified span is part of a
macro expansion however it does this by checking if the span is anything
other than a normal (non-expanded) kind, then the span sequence is
walked backwards to the root span.
This doesn't work when the MIR inliner inlines code as it creates spans
with expansion information set to `ExprKind::Inlined` and results in the
line number being attributed to the inline callsite rather than the
normal line number of the inlined code.

Don't carry MIR location in `ConstraintCategory::CallArgument`
It turns out that `ConstraintCategory::CallArgument` cannot just carry a MIR location in it, since we may bubble them up to totally different MIR bodies.
So instead, revert the commit a6b5f95fb028f9feb4a2957c06b35035be2c6155, and instead just erase regions from the original `Option<Ty<'tcx>>` that it carried, so that it doesn't ICE with the changes in #103220.
Best reviewed in parts -- the first is just a revert, and the second is where the meaningful changes happen.
We need this merge mechanism for inlined items but it's completely unwanted for impl blocks (at least the doc comments are, not the other attributes) since we want to keep what `cfg()` is put on the `pub use` or other attributes.
