panic.rs: fix docs (recover -> catch_unwind)

The current docs are a bit inconsistent. First, change all references of "recover" to "catch_unwind" because the function was renamed. Second, consistently use the term "unwind safe" instead of "panic safe", "exception safe" and "recover safe" (all these terms were used previously).

fe19b473d2 Rollup merge of #33820 - jonathandturner:format_readability_updates, r=nikomatsakis
Increase spacing in error format for readability.

Two small tweaks that seem to help readability quite a bit:
* Add spacing header<->snippet, but use the |> on the side for visual consistency
* Fix #33819
* Fix #33763
* Move format-sensitive test (issue-26480 in cfail) to ui test

80d733385a Inline simple Cursor write calls
Implementing the Write trait for Cursors over slices is so light-weight that under some circumstances multiple writes can be fused into a single instruction. In general I think inlining these functions is a good idea because most of the code can be constant-folded and copy-propagated away.

Closes issue #33916.

Perform `cfg` attribute processing during macro expansion and fix bugs

This PR refactors `cfg` attribute processing and fixes bugs. More specifically:
 - It merges gated feature checking for stmt/expr attributes, `cfg_attr` processing, and `cfg` processing into a single fold.
  - This allows feature gated `cfg` variables to be used in `cfg_attr` on unconfigured items. All other feature gated attributes can already be used on unconfigured items.
 - It performs `cfg` attribute processing during macro expansion instead of after expansion so that macro-expanded items are configured the same as ordinary items. In particular, to match their non-expanded counterparts,
  - macro-expanded unconfigured macro invocations are no longer expanded,
  - macro-expanded unconfigured macro definitions are no longer usable, and
  - feature gated `cfg` variables on macro-expanded macro definitions/invocations are now errors.

This is a [breaking-change]. For example, the following would break:
```rust
macro_rules! m {
    () => {
        #[cfg(attr)]
        macro_rules! foo { () => {} }
        foo!(); // This will be an error

        macro_rules! bar { () => { fn f() {} } }
        #[cfg(attr)] bar!(); // This will no longer be expanded ...
        fn g() { f(); } // ... so that `f` will be unresolved.

        #[cfg(target_thread_local)] // This will be a gated feature error
        macro_rules! baz { () => {} }
    }
}

m!();
```

Trait documentation clarifications

Hi! I've felt a bit of friction lately in figuring out how to write custom implementations of the `derive`able traits, so I decided to add to the docs :)

The docs for `Copy` are already excellent-- clear, useful sections that I only reordered a bit-- they're now:

* General explanation
* When can my type be `Copy`?
* When can my type _not_ be `Copy`?
* When should my type be `Copy`?
* Derivable
* How can I implement `Copy`?

I didn't add all these sections for all the traits, but I did make sure all the derivable traits had a consistent "Derivable" section that explained what the derived implementation does and a "How can I implement" section that has an example.

Please check me for correctness-- I tried to do research to make sure I was saying accurate things but I'm still learning! ❤️ I'd also love suggestions on information to add that is still missing-- I think these traits are important and deserve to have awesome docs!

This makes the \"shadowing labels\" warning *not* print the entire loop as a span, but only the lifetime.

Also makes #31719 go away, but does not fix its root cause (the span of the expanded loop is still wonky, but not used anymore).
