runtime: correct caller PC/SP offsets in walltime1/nanotime1

In walltime1/nanotime1, we save the caller's PC and SP for stack
unwinding. The code does that assumed zero frame size. Now that
the frame size is not zero, correct the offset. Rewrite it in a
way that doesn't depend on hard-coded frame size.

May fix #37127.
