Migrate `write.rs` to `rustc_ast::FormatArgs`
changelog: none
Part 1 of #10233
The additions to `clippy_utils` are the main novelty of this PR, there's no removals yet since other parts still rely on `FormatArgsExpn`
The changes to `write.rs` itself are relatively straightforward this time around, as there's no lints in it that rely on type checking format params

Mark Rust 1.68.0 as release in the changelog
Roses are red,
this poem is dead,
my creativity is lost,
outside there is frost?
Maybe I should really stop including a "roses are red" with every changelog PR. These are getting worse every time...

This is fixed by simply using the currently registered target in the
current session. We need to use it because of target json that are not
by design included in the rustc list of targets.
Include async functions in the len_without_is_empty
fixes#7232
Changes done to the functionality:
Allowing different error types for the functions was disallowed. So the following was linted before but is not after this change
```
impl Foo {
pub len(&self) -> Result<usize, Error1> { todo!(); }
pub is_empty(&self) -> Result<bool, Error2> { todo!(); }
}
```

At least for integers, shifts are already handled by the compiler.
----
