[VPlan] Make VPBlock constructors private (NFC).
16d19aa moved to manage block creation via VPlan directly, with VPlan owning the created blocks. Follow up to make the VPBlock constructors private, to require creation via VPlan helpers and thus preventing issues due to manually constructing blocks.
