IVGCVSW-2049 + IVGCVSW-2051 Create the CL Mean Float workload and add

the unit tests

 * Created the ClFloatWorkload class
 * Added ClMeanValidate validation function
 * Added helper function to convert the reduction axes from the ArmNN
   format to ACL's
 * Added workload tests
 * Added some unit tests
 * These changes need the CL pin to be pointing at least to revision

   ReduceMean in OpenCL)
