GLoader3D::onChangeSpine uses wrong spine API with cocos2d-x 4.0

GLoader3D::onChangeSpine uses incompatible calls to the spine AnimationState. The spine API in cocos2d-x 4.0 is quite different so the errors lead to the compilation errors in FairyGUI SDK.

You need to upgrade spine-runtime to 3.8 manually.
