[MachineOutliner] NFC: Remove insertOutlinerPrologue, rename insertOutlinerEpilogue

insertOutlinerPrologue was not used by any target, and prologue-esque code was
beginning to appear in insertOutlinerEpilogue. Refactor that into one function,
buildOutlinedFrame.

This just removes insertOutlinerPrologue and renames insertOutlinerEpilogue.
