Fix a problem with x_set_tab_bar_lines (Bug#46827)

Browse source 
* src/xfns.c (x_set_tab_bar_lines): Call
x_change_tab_bar_height only if the number of tab bar lines
changed from or to zero (Bug#46827).
* src/xterm.c (x_make_frame_visible): Make frame_size_history
update less noisy by doing it only if the frame wasn't visible
before.
