[Rebase][dev/m42] Vibration changes

Vibration is not signaled by ipc messages anymore. Instead, mojo is
used to call methods of a VibrationManager object living in the browser
process.

This patch implements this interface. It also provides a virtual
interface device::VibrationProviderClient

On ewk side, things are simplified: instead of having
Ewk_Vibration_Client and VibrationProviderClient. There is only one
class: VibrationProviderClientEwk, which implements
device::VibrationProviderClient
