API fluid.data/fluid.layers.data 报错信息增强 [仅涉及Python端]

paddle.fluid.data(name, shape, dtype='float32', lod_level=0)

paddle.fluid.layers.data(name, shape, append_batch_size=True, dtype='float32', lod_level=0, type=VarType.LOD_TENSOR, stop_gradient=True)

因为这2个接口的单测在同一文件，且通用之处较多，所以在同一个PR中修改。

1. 参数name的类型是str/unicode

• 报错样例：

TypeError: The type of 'name' in data must be (<type 'str'>, <type 'unicode'>), but received <type 'int'>.

2. 参数shape的类型是list/tuple

• 报错样例：

TypeError: The type of 'shape' in data must be (<type 'list'>, <type 'tuple'>), but received <type 'int'>.
