[pstl] Make the default backend be the serial backend and always provide parallel policies

Summary:
Before this change, the default backend was TBB but one could disable
anything related to TBB by removing the parallel policies. This change
uses the serial backend by default and removes the ability to disable
parallel policies, which is not useful anymore.
