Summary WebXR tests often fail due to running out of GraphicsContextGLs

SimulatedXRDevice::shutDownTrackingAndRendering() should clear its GraphicsContextGL to ensure the resource is cleaned up quickly, and doesn't wait for GC to be reclaimed. Without this, we can run out of GraphicsContextGLs (e.g. GraphicsContextGLOpenGLManager::hasTooManyContexts()) and fail tests if GC happens to be running a bit behind.

The test I used for this was: `run-webkit-tests imported/w3c/web-platform-tests/webxr/xrDevice_requestSession_immersive.https.html --repeat=40` Prior to this change it would fail periodically, now it passes 100%.
