Add new configure parameter for Xcb-Xlib

This adds a new configuration parameter, xcb-xlib, which allows
overriding the configure test for that existing configuration option.

The use of xcb-xlib in the xcb platform plugin becomes the preferred path
for non-OpenGL ES 2 builds, while the EGL codepath is used otherwise.
This has the advantage that EGL can be used with Desktop OpenGL if Qt is
configured with -no-xcb-xlib.
