Manipulators: move settings to ID properties

This makes manipulator access closer to operators,
and allows Python access.

This adds RNA for manipulators, but not Python registration yet.

- Split draw style into 2x settings:
  `draw_style` (enum) & `draw_options` (enum-flag)
- Rename wmManipulator.properties -> properties_edit,
  Use wmManipulator.properties for ID-properties.
  Note that this area of the API will need further work since
  manipulators now have 2 kinds of properties & API's to access them.
