Check and send usb state broadcast when devices boots

Broadcasts are not sent until BOOT_COMPLETED is received.
When the device boots with usb plugged, the UPDATE_STATE
for connted and configured would be received way before
BOOT_COMPLETED is received. Since, devices can continue
to stay in same usb configuration(set through persistent
property trigger), check and send a usb state broadcast
if needed.

BUG: 34451258
Test: Manually checked to verify the broadcasts sent.
