Fix ScopedGLContextChecker with QTWEBENGINE_DISABLE_GPU_THREAD=1

The ScopedGLContextChecker, which deactivates the current
QOpenGLContext when executing Chromium tasks, is currently enabled
only if QOpenGLContext::supportsThreadedOpenGL() is false. But the gpu
thread can nowadays be disabled also with an environment variable and
ScopedGLContextChecker needs to take this into account.
