Build the execution backend a policy asks for.

Parameters:

policy – Translated run policy.

A process-pool backend when the policy requires spawn (backend == "process", workers > 1, or parallel_mode == "isolated"); otherwise a serial backend carrying the policy’s checkpoint / failure flags. Timeout knobs apply only under the process-pool backend.
