Window::unresizable property is not respected in embedded mode (DisplayServer)

Issue description

Setting the window unresizeable flag does not seem to have an effect if the window is in embedded (single window) mode.

Tested it in the editor with a window node as well as in the editor with

set_flag(Window::Flags::FLAG_RESIZE_DISABLED, true);

In both cases the flag is set, but not respected as the user is able to resize regardless of the flag. Setting the flag to false also doesn't have the opposite effect, so it is probably ignored in embedded mode.
