IVGCVSW-3656 Make the reference backend optional

 * Made the build of the reference backend depend on a new ARMCOMPUTEREF
   macro
 * Made the relevant targets dependent on the ref backend
 * Moved Cl and Neon static registry initializers to separate files
 * Wrapped some of the unit tests into proper ifdefs where necessary
