Add a data type check for tvm.nd.array's API TVMArrayCopyFromTo. Lacking the
type check
leads to a value error in some situations.
For example, the user input x to a builded graph, the x has a shape of
[200,10] and has a dtype of 'float32'. When copying the x
to the NDarray placeholder with type 'float64' whose shape is [100,10], the
program doesn't report a warning, because it can pass the size check i.e.
200*10*32==100*10*64, however, every 64 continous bits in inputx is treated a
number and copyed to the new ndarray, the values change. because of different
hardcode. More importantly, this kind of error is implict.
