Move common device metrics code to InputDeviceMetricsSource
Move common device metrics code from InputDeviceMetricsCollector to
InputDeviceMetricsSource.
The common code moved is:
* enum class InputDeviceUsageSource
* InputDeviceUsageSource getUsageSourceForKeyArgs(int32_t, const NotifyKeyArgs&)
* set<InputDeviceUsageSource> getUsageSourcesForMotionArgs(const NotifyMotionArgs&)
This code will be used by both InputDeviceMetricsCollector,
which is a part of inputflinger as well as LatencyTracker,
which is a part of the dispatcher.
InputDeviceMetricsSource can be included in the places using the common code.
