Object: new add object tool, currently for primitive types

- Interactively adding primitives with two clicks.
- Scene orientation used for new objects.
- Depth [view-plane, axis-plane, surface]
- Origin [base, center]
- Primitive types [cube, cylinder, cone, uv-sphere, ico-sphere ]
- Settings for object types in the top-bar.

Shortcuts:

- Snapping (Ctrl).
- Constrain 1:1 aspect (Shift).
- Toggle center (Alt).

Part of T57210 design task.
