  [StackFrameLayoutAnalysis] Add basic Scalable stack slot output (#99883)

The existing StackFrameLayoutAnalysis details do not do well with
Scalable vector stack slots, which are not marked as scalable and
intertwined with the other fixed-size slots. This patch adds some very
basic support, marking them as scalable and sorting them to the end of
the list. The slot addresses are not really correct (for fixed as well
as scalable), but this prints something a little better with the limited
information curently available.
