On GTK do not inhibit implied resizing until tool bar was drawn (Bug#74750)

On GTK do not inhibit implied resizing until tool bar was drawn (Bug#74750)

* src/frame.c (frame_inhibit_resize): Under GTK do not inhibit
implied resizing as long as the tool bar has not been drawn yet
so the frame gets its intended initial height (Bug#74750).
* src/gtkutil.c (update_frame_tool_bar): Set tool_bar_resized
slot of frame f to true regardless of whether a tool bar was
made or not.  This will make inhibiting implied resizes work
again from now on.
