winrt: QWinRTEGLContext: add isValid functionality
QPlatformOpenGLContext::isValid always returns true
but it is possible that creation of the context fails
in QWinRTEGLContext. This case should be reflected in
isValid because other places (like QOpenGLContext::isValid())
rely on it and not having proper information about the
validity of the context might lead to crashes.
Task-number: QTBUG-67568
