  [ExprConstant] Handle shift overflow the same way as other kinds of overflow (#99579)

We have a mechanism to allow folding expressions that aren't ICEs as an
extension; use it more consistently.

This ends up causing bad effects on diagnostics in a few cases, but
that's not specific to shifts; it's a general issue with the way those
uses handle overflow diagnostics.
