efl_ui_win: Don't allow the frame object to change size before first draw

efl_ui_win: Don't allow the frame object to change size before first draw

This fixes a bug where calling:

evas_object_show(win);
evas_object_resize(win, 400, 400);
elm_run();

Would show a much smaller than 400,400 window on wayland, as the CSD
calcs would set the size smaller.

It also fixes some differences in startup size between X and wayland for
some trivial test clients.
