Cleanup HalInterfaces.h
Prior to this CL, HalInterfaces.h polluted the global namespace through
the "using" declarations. This CL creates a new ::android::nn::hal
namespace and places the names there instead.
This CL also changes the namespace of the Callback objects from
::android::hardware::neuralnetworks::V1_2::implementation to
::android::nn to be consistent with the other parts of frameworks/ml/nn.
