================================================
This should fix this (I cannot reproduce it):

Lately I added the geometry pointer to the item. This has indeed
the potential for an already deleted pointer being accessed.
This PR removes the geometry pointer from the item and relies on the
ViewProvider to indirectly access an updated pointer.

As reported:

Support for moving external geometry to another layer will come in the future.
============================================================
This class needs quite some rework, as it is mixing model-view model and item model.
Eventually, the whole needs to be moved to a QTreeWidget for layers' implementation.
This commit:
1. Moves back implementation only class item to the cpp file.
2. Adds a contextual submenu to change the selection from one layer to another in the
naive fixed 3 layer implementation.
3. Adds checkboxes to hide geometry.
It is the minimal modification to enable a user work with the 3 layer implementation.
* QString::indexOf() is now marked as [[nodiscard]]
* QApplication::fontMetrics() is deprecated, use the constructor of QFontMetricsF
* fix -Wunused-result

This commits removes the Geometry construction data member and adapts sketcher code to use
GeometryFacade to access construction information via the SketchGeometryExtension.
`Sketcher_ConstrainBlock` to `Constraint_Block`.
`Sketcher_ConstrainLock` to `Constraint_Lock`, and the corresponding
`_Driven` variant.
Adjust the icons in the taskpanel for the sketcher constraints,
elements, and for the action menu for constraints.
Adjust the icon order in the `Sketcher.qrc` resource file.
