Rollup merge of rust-lang#130244 - samueltardieu:qmark-expansion-span-fix, r=jieyouxu

Use the same span for attributes and Try expansion of ?

This is needed for Clippy to know that the `#[allow(unused)]` attributes added by the expansion of `?` are part of the desugaring, and that they do not come from the user code.

rust-lang/rust-clippy#13380 exhibits a manifestation of this problem and will be fixed by this change.
