Support devices that expose a MBIM interface.

This CL modifies UsbModemSwitchOperation to first check if the device
has a USB configuration that exposes a MBIM interface. If a MBIM
configuration exists, the switch operation completes by selecting that
configuration. Otherwise, the switch operation proceeds the same way as
it used to be by sending special USB messages.

BUG=chromium:349256
TEST=Tested the following:
1. Build and run unit tests.
2. Verify that mist successfully switches supported non-MBIM dongles
   from the mass storage mode to the modem mode.
3. Verify that mist successfully selects the MBIM configuration for
   supported MBIM dongles.
