Updated PASE PasscodeId to Always be 0 to Match Spec (#15924)

-- Removed PasscodeId from all APIs. -- When opening an ECM window, the passcodeID to use in PASE PBKDFParamRequest is always 0. -- Non-zero values of passcodeID in PASE PBKDFParamRequest are forbidden. -- Removed PasscodeId field in OpenCommissioningWindow command needs.
