bors 4a2fe4491e Auto merge of #120361 - compiler-errors:async-closures, r=oli-obk 
Rework support for async closures; allow them to return futures that borrow from the closure's captures

This PR implements a new lowering for async closures via `TyKind::CoroutineClosure` which handles the curious relationship between the closure and the coroutine that it returns.

I wrote up a bunch in [this hackmd](https://hackmd.io/`@compiler-errors/S1HvqQxca)` which will be copied to the dev guide after this PR lands, and hopefully left sufficient comments in the source code explaining why this change is as large as it is.

This also necessitates that they begin implementing the `AsyncFn`-family of traits, rather than the `Fn`-family of traits -- if you need `Fn` implementations, you should probably use the non-sugar `|| async {}` syntax instead.

Notably this PR does not yet implement `async Fn()` syntax sugar for bounds, but I expect to add those soon (**edit:** #120392). For now, users must use `AsyncFn()` traits directly, which necessitates adding the `async_fn_traits` feature gate as well. I will add this as a follow-up very soon.

r? oli-obk

This is based on top of #120322, but that PR is minimal.

Nadrieril a2dcb3a6d9 Disallow an arm without a body (except for never patterns) 
Parsing now accepts a match arm without a body, so we must make sure to
only accept that if the pattern is a never pattern.
