Shadowing / Culling

* Removed useless and outdated ShadowMapPlugin docs.

* Consistified WebGLState, added culling.

* Let WebGLShadowMap set culling through WebGLState.

* WebGLShadowMap: Removed redundant state setup.

* WebGLRenderer: Removed needless factorization.

* Removed cull state mess from WebGLShadowMap.

- Instead flip .side on the depth material with the same effect.
- See #8760.

* Updated builds.
