Changes iAP2 Bluetooth to USB switching flow

These changes update switching flow so now instead of automatic
switching start in case of same UUID is detected SDL will wait for
external signal from the system to start this flow.
Also due to UUID is reliable only while device remains connected (at
least on certain systems) SDL now uses Bluetooth MAC and USB serial to
manage devices and UUID is used only for detection of devices able to
switch their transports. Currently only iAP2 Bluetooth to USB support is
implemented.
