749349fc9f Refactor async fn return type lowering 
async fn now lowers directly to an existential type declaration
rather than reusing the `impl Trait` return type lowering.

As part of this, it lowers all argument-position elided lifetimes
using the in-band-lifetimes machinery, creating fresh parameter
names for each of them, using each lifetime parameter as a generic
argument to the generated existential type.

This doesn't currently successfully allow multiple
argument-position elided lifetimes since `existential type`
doesn't yet support multiple lifetimes where neither outlive
the other. This requires a separate fix.

Rollup merge of #57565 - petrochenkov:turbowarn, r=Centril 
syntax: Remove warning for unnecessary path disambiguators

`rustfmt` is now stable and it removes unnecessary turbofishes, so removing the warning as discussed in https://github.com/rust-lang/rust/pull/43540 (where it was introduced).
One hardcoded warning less.

Closes https://github.com/rust-lang/rust/issues/58055

Filter ui revision tests

Updates UI test output filtering to also filter away test annotations for revisions:

Previously filtered: //~ ERROR [XXXX]
Now also filters: //[revision]~ ERROR [XXXX]

I reckon, if we have the one, we should have the other for consistency, its lack was probably an oversight (the existence of revision testing is not really well documented...)
