chore: Wrap VRC dependencies and VRCAvatarDescriptors (#504)

* add version defines

* refactor: prefer BuildContext.ctor() overload taking GameObject

* wrap unit tests entirely with MA_VRCSDK3_AVATARS

* wrap unit tests smart with MA_VRCSDK3_AVATARS

* wrap runtime entirely with MA_VRCSDK3_AVATARS

* wrap VRC.SDKBase.IEditorOnly with MA_VRCSDK3_AVATARS

* wrap editor entirely with MA_VRCSDK3_AVATARS

* fix AvatarObjectReference.Get(Component)

* wrap editor smart with MA_VRCSDK3_AVATARS

* wrap BuildContext smart with MA_VRCSDK3_AVATARS

* wrap PluginDefinition smart with MA_VRCSDK3_AVATARS

* style: move conditional compiles one step outside
