ANGLE_platform_angle_device_context_volatile_* extensions Change from Kimmo Kinnunen downstream: https://bugs.webkit.org/show_bug.cgi?id=216106 Add two extensions for EAGL and CGL backends to declare the underlying platform context being "volatile". It means that the thread-global current context is being modified behind ANGLE. If ANGLE context is marked volatile for a particular API, it will sync the underlying context for every EGL function that needs the context. Most intuitive use is for the client to call eglMakeCurrent before calling any gl function if the client knowns the platform state might be dirty. Implement eglReleaseThread for EAGL and CGL backends. Releasing thread will unset the platform current context. Fix a bug of omitting EGL_ANGLE_device_eagl from being advertised.
