Make compatible with Unity 6 projects (#1232)

* Disable compilation for use in Unity 6 (6000.0.20f1):
- Do not compile some classes and code paths in non-VRChat projects.
- This has been tested in Unity 6 (6000.0.20f1).

* Fix hide internal components in Unity 6:
- [AddComponentMenu("")] does not work in Unity 6.
- Replace it with [AddComponentMenu("/")]
- This alternative is confirmed to also work in Unity 2022.
