BUG: Make Series flex methods (truediv, floordiv, etc.) raise NotImplementedError for bool dtypes

This change ensures that flex methods like .truediv(), .rtruediv(), .floordiv(),
.rfloordiv(), .pow(), .rpow() raise NotImplementedError for boolean dtypes,
consistent with their dunder method counterparts (__truediv__, etc.).

Previously, pd.Series([True]).truediv([True]) would return a float result,
while pd.Series([True]) / [True] would raise NotImplementedError. This fixes
the inconsistency by routing _binop through ops.arithmetic_op which includes
the bool dtype check.

Closes #63250
