Add support for external lazy camera HALs
The lazy camera provider HAL will be started when
a device is attached (USB hotplug) or opened and
then shut down when there are no active clients using it.
When a USB device is unplugged, the provider removes the camera
devices associated with it.
Test: atest CtsCameraTestCases
Test: atest cameraservice_test
Test: -Boot device with/without camera attached.
-(plug-in camera)
-Open app that uses camera
-adb shell ps | grep camera
-> shows "android.hardware.camera.provider@2.7-external-service-lazy"
- Close app and wait 5-10 seconds
- adb shell ps | grep camera
-> does not show "android.hardware.camera.provider@2.7-external-service-lazy"
