Rollup merge of #53545 - FelixMcFelix:fix-50865-beta, r=petrochenkov 
Fix #50865: ICE on impl-trait returning functions reaching private items

Adds a test case as suggested in #50865, and implements @petrochenkov's suggestion. Fixes #50865.

Impl-trait-returning functions are marked under a new (low) access level, which they propagate rather than `AccessLevels::Reachable`. `AccessLevels::is_reachable` returns false for such items (leaving stability analysis unaffected), these items may still be visible to the lints phase however.

Lament the invincibility of the Turbofish

Here a test case is added to ensure that any others attempting to drive the Turbofish to extinction have second thoughts. Previously the [entire test suite would succeed](https://github.com/rust-lang/rust/pull/53511) if generic arguments were accepted without disambiguation, making for [confusing and heartbreaking circumstances](https://github.com/rust-lang/rfcs/pull/2527).

Rollup merge of #53503 - kornelski:master, r=dtolnay 
Discourage overuse of mem::forget

Some uses of `mem::forget` have been replaced by better methods of `Box`, so I've removed obsoleted use-cases from these docs.

I've removed emphasis on leaking, because it's not obvious `mem::forget` does not guarantee leaking of memory: memory of stack-allocated objects and values partially moved out of `Box` will still be freed. That's a potential error when used to pass objects to FFI, so it's better to direct users to `Box::into_raw` instead.

Stabilize a few secondary macro features

- `tool_attributes` - closes https://github.com/rust-lang/rust/issues/44690
- `proc_macro_path_invoc` - this feature was created due to issues with tool attributes (https://github.com/rust-lang/rust/issues/51277), those issues are now fixed (https://github.com/rust-lang/rust/pull/52841)
- partially `proc_macro_gen` - this feature was created due to issue https://github.com/rust-lang/rust/issues/50504, the issue is now fixed (https://github.com/rust-lang/rust/pull/51952), so proc macros can generate modules. They still can't generate `macro_rules` items though due to unclear hygiene interactions.

Fixes #52913. This doesn't address the core problem, which is tracked by https://github.com/rust-lang/rust/issues/47206. However, it fixes the stable-to-stable regression: you now have to enable `#![feature(generic_associated_types)]` to trigger the weird behaviour.

3045ffa512 52985: better cycle error for existential types 
- Original cycle error diagnostics PR'd against this issue caught
panic-causing error while resolving std::mem::transmute calls
  - Now, catch invalid use case of not providing a concrete sized type
behind existential type in definining use case.
  - Update relevant test to reflect this new error

52985: revert normalize query changes
      - PR 53588 invalidates 53316, causing a correct cycle error to occur
    with a good span.
      - Don't need to revert the whole merge as the test files are
    still fine, just need to revert the normalize query changes.
      - It should now be correct that infinite recursion detected during
    normalize query type folding is a bug, should have been caught earlier
    (when resolving the existential type's defining use cases).

52985: code review impl
  - Only cause cycle error if anonymous type resolves to anonymous type
that has the same def id (is the same type) as the original (parent)
type.
  - Add test case to cover this case for existential types.

52985: remove Ty prefix from TyAnon
  - To align with changes per commit 6f637da50c56a22f745fd056691da8c86824cd9b
