gh-150817: Speed up Flag bitwise operations (GH-150824)
Flag.__or__, __and__ and __xor__ walked both operands on every call to reject
None values. Run that scan only when one of the operand values is actually
None, so valid combinations skip it. The TypeError and its message are
unchanged for the invalid cases.
