Gizmo: move spin tool axis option into gizmo-group

Having this setting here wasn't correct (the operator ignores it).

Gizmo: support for gizmo-group properties

This allows gizmo groups to store properties in the tool.
This makes sense for gizmo options which only control gizmo display and
don't control operator execution.

Unlike similar kinds of properties,
this isn't accessible via the gizmo-group-type instance.

For now the it's only stored in the workspace tool as can be done for
operator properties, so each instance doesn't have different settings
which would be confusing from a user perspective and complicate access
from the top-bar.

Later we could add gizmo-group properties if needed.
