Implement GLSurfaceQt and exclude chromium's implementation

This makes it possible to use the same EGLConfig that
is used by Qt when initializing the EGL surface instead
of relying on eglChooseConfig.
We can use the native interface to query the used config
from Qt to avoid EGL_BAD_MATCH errors during initialization.
This depends on patches in the qtbase dev branch, which will
become Qt 5.4 at some point, therefore we can only merge this
patch if we make Qt 5.4 a hard-dependency of QtWebEngine.
