RootCanal: Implement the control command set_device_configuration

This specific commands lets a tester change the configuration
of a connected device at runtime.

This requirement originates from the PTS-bot test runner
version 8.4.1, which requires different, non compatible dongles
for different tests (e.g. LE only v5.4+ for LE audio tests and
Dual v5.0- for A2DP tests).

The alternate solution would be to open multiple HCI ports
for all required configurations, but it does add complexity
to the test configuration whereby set_device_configuration
can be invoked prior to a test execution.
