IVGCVSW-4915 Improving messages around SAMPLE_DYNAMIC_BACKEND_ENABLED
* If SAMPLE_DYNAMIC_BACKEND_ENABLED is enabled but DYNAMIC_BACKEND_PATHS is not set then the user gets failing tests cases with no clear idea what has gone wrong. Explicitly failing when DYNAMIC_BACKEND_PATHS has not been set. * Adding an FAQ entry describing how the user can get confused by our documented usage of CMake.

In some error scenarios of calls to armnn::Optimize a null pointer may be returned. This contravenes the function documentation however, it can happen. Users are advised to check the value returned from the function as a precaution.
If you encounter this problem and are able to isolate it consider contributing a solution.

+Adding or removing -Dxxx options when building ArmNN does not always work.
+---------------------------------------------------------
+
+ArmNN uses CMake for build configuration. CMake uses a cumulative cache of user options. That is, setting a value once on a cmake command line will be persisted until either you explicitly change the value or delete the cache. To delete the cache in ArmNN you must delete the build directory.
