Finish work on collecting execution duration. Add tests and execution state enforcement.
Fix bug: Execution durations reported by HAL were not
reported properly through NDK.
Ensure execution duration is reported as UINT64_MAX on error paths.
Switch SampleDriver from system_clock to steady_clock.
Clarify, enforce, and validate that several ANeuralNetworksExecution_*
methods must not be called once execution has been scheduled.
Enforce and validate that ANeuralNetworksExecution_setMeasureTiming
can only be called in conjunction with
ANeuralNetworksCompilation_createForDevices with numDevices = 1.
Enforce and validate that ANeuralNetworksExecution_getDuration must
not be called until execution has finished.
Test: NeuralNetworksTest_static
Test: --gtest_filter=IntrospectionControlTest.SimpleAddModel with
setprop debug.nn.vlog driver,execution; by inspection of logcat,
verify that driver and runtime report the same duration
