Api Switch 增强输入类型检查 [仅涉及python端]

class paddle.fluid.layers.Switch(name=None)

检查成员函数case(condition)的输入condition:

• 检查类型是否为Variable
• 检查数据类型是否为"bool",

报错样例：

TypeError: The data type of 'condition' in the member function case of fluid.layer.Switch must be ['bool'], but received float32. 

TypeError: The type of 'condition' in the member function case of Switch must be <class 'paddle.fluid.framework.Variable'>, but received <type 'int'>.
