In anticipation of moving pred list building before inlining, use the common block split utility instead of custom code. This does a better job of propagating IL offsets, and automatically handles pred list maintenance.

Contributes to #80193.

Nice cleanup! I wonder how many other places we have where we do something that we already have a helper for. It also seems that fgSplitBlockAfterStatement might be even more correct because it has special handling for e.g. switches
