Handle inhibiting implied resizing for frames without initial tool bar

* src/xfns.c (x_set_tool_bar_lines, x_change_tool_bar_height)
* src/pgtkfns.c (x_change_tool_bar_height)
(pgtk_set_tool_bar_lines): Set f->tool_bar_resized to true so
inhibiting implied resizing works for frames without initial
tool bar too.  See the thread
https://lists.gnu.org/archive/html/emacs-devel/2025-08/msg00034.html.
