runtime: split PCs out of scase

Per-case PCs are only needed for race detector builds, so this allows
skipping allocating stack space for them for non-race builds.

It's possible to arrange the PCs and order arrays consecutively in
memory so that we could just reuse the order0 pointer to identify
both. However, there's more risk of that silently going wrong, so this
commit passes them as separate arguments for now. We can revisit this
in the future.

Updates #40410.
