Import mesh colors in 8BPP. 

* Colors were imported as 16BPP (half float)
* Far most common use cases only require 8BPP
* If you need higher data precision, use a custom array, which are supported now.

**WARNING**: 3D Scenes imported in 4.0 no longer compatible with this new format. You need to re-import them (erase them from .godot/import)
