Describe
The cinn-graph may hasn't input for CINN now support
fill_constant, and it's all inputs may generated by fill_constant instead of by fetch.So we remove the input check in InferShape, and rewrite the
GetExpectedKernelTypefor the base function may error when the op hasn't input.The new
GetExpectedKernelTypeinfer the kernel type from output, it's tensor has been initialized before (otherwise the default type isDataType::UNDEFINED).
