IVGCVSW-5676 Fixing build failure in backends jenkins job.

* Adding ref backend "ifdef" around ref test cases in
  NeonLayerTests_NDK_Bug.cpp
* Removing unnecessary includes from NeonLayerTests_NDK_Bug.cpp.
* Removing unnecessary include from NeonLayerTests.cpp
* Breaking up Backends_Capability_Test into one per backend to allow
  for conditional compilation.
* Remove unnecessary printout in src/backends/neon/test/CMakeLists.txt
