Fix required for Mojarra Issue 4388 / Scripts with CDATA cause "empty response" error on Ajax render

Ref: https://github.com/javaserverfaces/mojarra/issues/4388

–

The RenderKitImpl (com.sun.jsf-impl) class is returning a wrong configured ResponseWriter on partial responses. It is breaking the xhtml when it contains a javascript with CDATA; the final xhtml has a bad closed nested CDATAs.

The JSF 2.2.15 RenderKitImpl: https://github.com/javaserverfaces/mojarra/blob/2.2.15/jsf-ri/src/main/java/com/sun/faces/renderkit/RenderKitImpl.java
The JSF 2.3.5 RenderKitImpl: https://github.com/javaserverfaces/mojarra/blob/2.3.5/jsf-ri/src/main/java/com/sun/faces/renderkit/RenderKitImpl.java

https://github.com/javaserverfaces/mojarra/commit/ee3671db95986395e3a40a591c52522421b25bf2

The issue is fixed on JSF 2.3.9 reverting those above commits.
