Timer for pending incoming HID connections

HID devices may attempt HID connection immediately after the pairing. The Settings app may not have requested the profile connection by the time the incoming HID connection request is processed. So the incoming connection request may be rejected right away.
This change along with aosp/3502023 now waits for the local connection request before rejecting the incoming HID connection.
