Use block policy state instead of parked state to determine if a policy was violated

Summary:
Bubble the block policy state up through ConnectTip so the caller can more
robustly short circuit when a block policy fails (and not just assume that
a policy failed because a block was parked).

Depends on D13482

Test Plan:
