Rollup merge of #109354 - Swatinem:rm-closureid, r=compiler-errors

Remove the `NodeId` of `ast::ExprKind::Async`

This is a followup to https://github.com/rust-lang/rust/pull/104833#pullrequestreview-1314537416.

In my original attempt, I was using `LoweringContext::expr`, which was not correct as it creates a fresh `DefId`.
It now uses the correct `DefId` for the wrapping `Expr`, and also makes forwarding `#[track_caller]` attributes more explicit.
