Stabilize `std::io::ErrorKind::CrossesDevices`
FCP in #130191
cc #86442
See #130191 for more info and a recap of what has happened up until now.
TLDR: This had been FCP'd in December 2022 with some other `ErrorKind`s, but the stabilization got postponed due to some concerns voiced about several of the variants. However, the only concern ever voiced for this variant in particular was a wish to rename this to `NotSameDevice` analogous to Windows's `ERROR_NOT_SAME_DEVICE` (as opposed to Unix's `EXDEV`). This suggestion did not receive any support. So let's try to FCP this as is.
r? libs-api
This mainly aids in error recovery but also makes it a bit easier to handle lifetime resolution.
While doing so it also came apparent that we were not actually lowering lifetime outlives relationships within lifetime parameter declaration bounds, so this fixes that.

Revert #133817
This reverts commit 0585134e709de4a14e509158662fa569c155c195, reversing changes made to 5530869e0ff21d69e0eef1a4c4fd1f25bcbe7fbf.
#133817 unfortunately only converted the `println!` instances to `eprintln!`, meaning that some test output (via compiletest/bootstrap) was messed up because stdout/stderr output interleaved improperly when some `println!` instances were converted to `eprintln!` instances, while some `print!` instances remain unchanged. This made reading test output annoying for contributors cc #133879.
Closes#133879 by reverting.
#133817 can be relanded in the future when `print!` instances are also matched with `println!` instances.

This is a clean revert so I'm going to self-approve this PR.
Add a new test ui/incoherent-inherent-impls/no-other-unrelated-errors to check E0116 does not cause unrelated errors
rustc xxx (we do not know) to 1.82.0 emits unrelated errors when E0116 is present (see #125814).
We do not know what caused and fixed it, but add a test to confirm rustc does not cause the same error in the future.
No need to create placeholders for GAT args in confirm_object_candidate
We no longer need this logic to add placeholders for GAT args since with the removal of the `gat_extended` feature gate (https://github.com/rust-lang/rust/pull/133768) we no longer allow GATs in dyn trait anyways.
r? oli-obk
Rename `core_pattern_type` and `core_pattern_types` lib feature gates to `pattern_type_macro`
That's what the gates are actually gating, and the single char difference in naming was not helpful either
