Description
I had this idea while working on #16835
It would be cool when a type alias is used it gave like a hint that of what type it was like we do inline type hints.
So in the case above it would contain a shadowed out
(Arc<tt::Subtree>, SyntaxFixupUndoInfo, Span)
right after the MacroArgResult

Research direction
Start by reviewing the related issue #16835 and the existing inline type-hint behavior referenced in the description. The intended result is an inlay hint showing the underlying type immediately after a type alias use, such as MacroArgResult displaying (Arc<tt::Subtree>, SyntaxFixupUndoInfo, Span).
