[ML][Common] Add TensorsInfo getters / setters

ACR: TWDAPI-273

Methods added:
TensorsInfo.getTensorName
TensorsInfo.setTensorName
TensorsInfo.getTensorType
TensorsInfo.setTensorType
TensorsInfo.getDimensions
TensorsInfo.setDimensions

Test code:

var ti = new tizen.ml.TensorsInfo();
ti.addTensorInfo("tensor1", "UINT8", [1, 1])
console.log(ti.getTensorName(0));
ti.setTensorName(0, "changedName");
console.log(ti.getTensorName(0));
console.log(ti.getTensorType(0));
ti.setTensorType(0, "INT8");
console.log(ti.getTensorType(0));
console.log(ti.getDimensions(0));
ti.setDimensions(0, [2,4]);
console.log(ti.getDimensions(0));

[Verification] Built successful, tested in Chrome Dev console.
