Improve XYOnRotation axes
This MR rework the
XYOnRotation device in order to provides few other features.
- Added test for the default controller
use_dial_rotas an optional parameter to use dial (instead of user position) for the rotation
- Make sure real motors units are consistent
- Autogenerate calc motors units (there is no need to configure them as it have to be the same as the real motor unit)
- Use rotation axis unit to handle deg/rad (radian property is deprecated, but is still working)
