IVGCVSW-3177 Refactor Floor reference workload

 * Renamed RefFloorFloat32Workload to RefFloorWorkload
   and updated references to reflect this change.
 * RefFloorWorkload now uses Decoders/Encoders and
   supports the use of multiple data types.
 * Deleted FloorTestImpl.hpp and moved its contents
   into LayerTests.hpp.
