Improved static geometry performance, vertex color support

Support color vertex for 3DObject. 3DObject must include vertex colors in the gltf/glb

• New effect parameter: enable vertex color
• New 3DObject ACE: enable vertex color
• A new main.js is required in projects to support vertex color, see the main.js in 3d-object-vertex-color.c3p
• The vertex colors _must_ be in the format of float vec3 (e.g. no alpha color)

Improved static geometry performance for non-worker animation mode. Depending on the 3D model properties (size of meshes, number of textures, number of meshes, etc.) static geometry mode performance can increase by 2X-10X. In some cases with lower animation FPS, it will also improve performance of animated models with static geometry set (in non-worker animation mode.)

Worker mode animation static animation performance should not have changed.
