Rotary encoder rotation count telemetry

Implements a telemetry using the Telemetry Express API to log full
rotations on rotary encoder devices. By default, logs are disabled for
rotations. A rotary input device can change the minimum logged rotation
value via the `rotary_encoder.min_rotations_to_log` IDC property, by
setting it to a positive integer value.
