Improved testing for ArgMinMax

* ArgMinMax output was fixed to S32, this patch makes the changes required
  to allow other output types like U64/S64

* Made changes to the ArgMinMax fixture and tests to allow specifying output data type.

* Made changes to the reference reduction_operation to allow specifying the output type

* Added tests case to output S64 for the CL backend.

* Added missing test cases in the neon backend.

* Partially resolves MLCE-1089
