Fix display of line numbers in GTK builds
* src/xdisp.c (should_produce_line_number) [USE_GTK]: Make sure
tip_frame is indeed a tooltip frame, before disabling line numbers
on it. (Bug#27647)
* src/dispextern.h (tip_frame): Add commentary describing the
kludgey usage of this variable in GTK builds.
