Fix #142285: 3D cursor placement ignores unselectable objects

This was caused by 3dfec1ff73
which introduce the new behavior. This was to fix workflows
using a lot of semi-transparent objects which made nagivation
difficult.

This patch first roll back to the previous behavior: The
unselectable object will affect depth-aware operators.

This patch introduces a new visibility property to remove
the influence of objects in all depth picking operations
and selection operations. However the object is still
selectable through non-drawing selection operators
(e.g. select by material) and through the outliner.
This is to adress the aforementionned navigation issues.
