Wireframe Mode: Fix missing wireframe if overlays are disabled

gpu.types.GPUOffscreen.py example file: Move the shader reference removal code to execute on __main__

Viewport: tweak shading pie layout and naming.

Cleanup: Indentation

Multires: Remove unused field from reshape context

gpu.types.GPUOffscreen.py example file: Delete the reference of the previous shader.

Strange that the `bpy.utils.register_class` utility does not remove the reference of the class with same name.

Viewport: tweak shading pie menu to have X-ray on same side as wireframe.

Viewport: change Z key to shading pie menu to switch mode, X-ray and overlays.

This lets us do the most common shading switching with one shortcut. We keep
alt+Z and shift+Z for quickly toggling to lookdev and rendered mode and back,
it's debatable which settings deserve a dedicated shortcut like this.

The downside is that switching X-ray is a little slower, and that there is
some risk of accidentally going to lookdev or rendered mode which can be slow
to cancel.

Fix: missing cache invalidation when the active vertex group changed

Differential Revision: https://developer.blender.org/D3716

Edit Mesh Mode: Increase Face dot Z bias

Edit Mode: Merge Xray and "Limit selection to visible" options behaviour

We now treat Xray as being the mode where Limit selection to visible is off.
If Xray is OFF, Limit selection to visible is considered ON.

To allow 'see through wires' with solid shading (not Xray shading) we still
draw solid shading if Xray is ON with Xray Alpha set to 1.0.

DRW: Add back wireframe mode

This is using the existing engine (workbench forward) with 0.0 xray_alpha
and forcing wireframes on all objects.

There is no workflow/shortcut changes in this commit.

Cleanup: Inetnation

Multires: Support masks propagation to higher levels

Multires: Copy mask from sculpt to multires

Allows to paint mask in sculpt mode, then go out of sculpt
mode, come back and see proper mask.

Subdiv: CCG, initialize grid mask from paint mask

Subdiv: CCG, cleanup

Re-enable FBX add-on.

Depsgraph: update frame in scene on frame change.

Normally the time can be read from DEG_get_ctime(depsgraph), but this is a
bit more forgiving for e.g. addons that don't care too much about the details
of the COW depsgraph.

Fix smoke to render in Cycles again.

Viewport caching seems still broken, though baking works.
