Revise the reporting of the special stack slots for OSR to be more uniform. * Always record the original method FP-relative offset. * Always apply the same adjustment for original method slosts i the OSR frame * Handle caller-SP relative adjustment in `lvaToCallerSPRelativeOffset` In particular, this fixes dotnet#43534 where we were reporting the wrong caller SP for the profiler exit hook.
