IVGCVSW-5985 Remove deprecated code

 * Removes deprecated AddLayer, IsLayerSupported functions
 * Marks the whole LayerVisitor class as deprecated not just the
   constructor. This required to wrap all Accept functions in a
   no deprecate macro because the LayerVisitor is used as a parameter in
   there
 * Removes usage of deprecated LayerVisitor and replaces it
   with ExecuteStrategy. This required a few structural changes
   in the unit tests
 * Adds a default implementation for IStrategy called StrategyBase
 * Changes pyarmnn to use non deprecated constructor for
   INetworkProperties and adds related unit test
 * Marks usage of deprecated code in pyarmnn as deprecated. This
   required to extend INetworkProperties to allow backwards compatibility
 * Removes deprecated functions from CpuAcc, GpuAcc and Ref backends

Note: This patch breaks compatibility with backends that are not
      updated in this patch
