Add support for arbitrary parameters for CPU Gather
* The shape of input and indices tensors, and the gather axis
can be any number, as long as these are valid and the output
tensor doesn't have more dimensions than the library supports.
* Update the reference code to be more generic and straightforward.
* Add necessary test cases.
