Fix studio python samples when running on CRD

Browse Source 
* Changed window.cc to not pass `SDL_WINDOW_OPENGL` for headless opengl graphics modes since this requests a [GLX visual](https://tronche.com/gui/x/xlib/window/visual-types.html#Visual) but CRD's virtual X11 display has no GLX visuals causing window creation to fail with "Couldn't find matching GLX visual".

* Changed `TryLoadEgl` so it fails if `eglBindAPI(EGL_OPENGL_API)` does not return true, causing `CreateFilamentPlatform` to fallback to OSMesa on CRD.
