XCB: Remove the native X11 painting engineHEADdev

This is a reversal of commit 07942adb77f60738a6043665673d51fc7991233b,
which brought the older Qt 4 engine back into Qt 5. This code is
unmaintained and has only had minor bug-fixes applied to it since it was
brought back.

It doesn't remove the querying of the XRender extension that the commit
above added, because it's required by the Cursor support.

[ChangeLog][Important Changes] The experimental X11 Native Rendering
engine has been removed. Use of this engine required enabling it at
compile time with a CMake option and enabling at runtime with an
environment variable.
