RESTRICT AUTOMERGE Disallow unexpected incoming HID connections 2/2

HID profile accepted any new incoming HID connection. Even when the
connection policy disabled HID connection, remote devices could initiate
HID connection.
This change ensures that incoming HID connection are accepted only if
application was interested in that HID connection.
This vulnerarbility no longer exists on the main because of feature
request b/324093729.

Test: Manual | Pair and connect a HID device, disable HID connection
from Bluetooth device setting, attempt to connect from the HID device.
