[PORT FROM R4]lis3dh: Send init events to userspace when status changes

BZ: 39086

In some use case, when sensor device's status changes, such as
enable/disable, interrupt/polling mode switching. Android framework
doesn't have enough accelerometer data to set window orientation
correctly, so we need to send them manually.
