stransky f2dd95dadb Bug 1795851 [Wayland] Update EGL window size/scale in moz_container_wayland_get_egl_window() r=emilio
We need to return correct EGLWindow from moz_container_wayland_get_egl_window() with correct scale/size
and also keep the EGLWindow up to date. In this patch we do:

- Implement moz_container_wayland_egl_window_needs_size_update() and use it in nsWindow::SetEGLNativeWindowSize().
  Avoid redundant moz_container_wayland_egl_window_set_size()/moz_container_wayland_set_scale_factor() calls as it may lead to resize callback calls to MESA.
- If wl_container::eglwindow is present, check its size/scale in moz_container_wayland_get_egl_window() and update size/scale if needed.
- Use nsIntSize single param instead of width/height pairs in some moz_container_* functions.
- Assert when gtk_widget_get_window(container) returns null.
