Oliver Stannard 67200f5dc8 [ARM] Tidy up stack frame strategy code (NFC) (#110283) ...

We have two different ways of splitting the pushes of callee-saved
registers onto the stack, controlled by the confusingly similar names
STI.splitFramePushPop() and STI.splitFramePointerPush(). This removes
those functions and replaces them with a single function which returns
an enum. This is in preparation for adding another value to that enum.

The original work of this patch was done by James Westwood, reviewed as
 #82801 and #81249, with some tidy-ups done by Mark Murray and myself.
