Merge #3047

3047: Update async unsafe fn ordering in parser r=matklad a=kiljacken

As of rust-lang/rust#61319 the correct order for functions that are both unsafe and async is: `async unsafe fn` and not `unsafe async fn`.

This commit updates the parser tests to reflect this, and corrects parsing behavior to accept the correct ordering.

Fixes #3025
