JFonS c571e4a7f4 Implement distance fade and transparency
The built-in ALPHA in spatial shaders comes pre-set with a per-instance
transparency value. Multiply by it if you want to keep it.

The transparency value of any given GeometryInstance3D is affected by:
   - Its new "transparency" property.
   - Its own visiblity range when the new "visibility_range_fade_mode"
     property is set to "Self".
   - Its parent visibility range when the parent's fade mode is
     set to "Dependencies".

The "Self" mode will fade-out the instance when reaching the visibility
range limits, while the "Dependencies" mode will fade-in its
dependencies.

Per-instance transparency is only implemented in the forward clustered
renderer, support for mobile should be added in the future.
