Support tensor cache while create tensor
Tensor can be shared between different operations, if tensor have
identical data and quantization parameter, they should share same
low-level tensor object to save memory.
In tim-vx, introduce a tensor cache which key is md5sum and value is
low-level tensor object. If up-coming tensor have same md5sum, the
cached tensor object reused for tensor creation.

* Fixed the IOtensor order difference between src_graph and infer_graph
Graph Input/Output tensor sequence may changed after graph
transformation(layout infer), it is difficult to get the IO mapping
between original graph and final graph.
Clients such as the Android Support Library create tensors using the
original input/output order, which may not be the same as the input
order of src_graph, the data can not be setup correctly.
Solution:
Decide the order of inputs/outputs while creating tensor not at binding to
operation. The order of binding could be change in each transform.
