COMPMID-2707: add keep_dims parameter to Reduction Operation

The added parameter is used to decide whether or not to keep
the target dimension of reduction operation. ArgMinMax operations
will always remove the reduced dimension. Following things
are updated to support the parameter.

- [CL/NEON] functions and reference kernel
- [CL/NEON] ArgMinMax function to use ReductionOperation function
- [CL/NEON] validation test suite for Reduction and ArgMinMax operations
  to validate the added parameter
- ReductionOperationFixture is modified NOT to pre-populate output
  tensor and now relies on underlying kernel/function.
- Adjust CL validation test suite for Reduction operation to remove
  excessive test cases with axis values beyond input tensor's
  dimension.
