Follow up to fix for T73684,
which allowed some modal gizmos to hide all others.
Also resolve an issue from 917a972b56
where shear the shear gizmo would be visible during interaction.
Internally there are some changes to gizmo behavior
- The gizmo with modal interaction wont draw if it's poll function fails.
- The WM_GIZMOGROUPTYPE_DRAW_MODAL_ALL flag now causes these gizmo
groups to draw when another group is being interacted with.
