MLCE-233 Added ability to enable fast_math through the NNAPI driver

 * Added -a command line option to enable fast_math on Neon/CL when launching the NNAPI driver
 * The invocation will look something like:
   /vendor/bin/hw/android.hardware.neuralnetworks@1.3-service-armnn -v -c GpuAcc -n arm-armnn -a
 * Enabling fast_math may cause an increase in VTS or CTS test failures due to a change in precision
