Fix Scene3D shader cache miss

Fix Scene3D shader cache miss

1. Hash include THREE_TEX eash items.
   It will reduce some shader hash collision.
2. Make vertex color use ifdef in shader level.
   (Since we'd better skip to allocate vertex color attribs in usal case)

TODO : Current shader-define-factory.cpp implement has various problem.
We should refactorize this code, and re-open UTC soon
