Camera: Play shutter sound in absence of CAMERA_MSG_SHUTTER

When shutter sound is ON, even if application calls takePicture
without CAMERA_MSG_SHUTTER, the camera service should still play
shutter sound.

Also remove the code using ro.camera.sound.forced since it's
not used any more.

Test: 3rd party app on device with enforced shutter sound
