Fix tool-tip display when display margins are non-zero by default
* src/buffer.h (bset_left_margin_cols, bset_right_margin_cols):
New inline functions.
* src/xfns.c (Fx_show_tip):
* src/w32fns.c (Fx_show_tip): Force display margins of the tip
buffer to zero, as it will be displayed in a pseudo-window, which
doesn't support display margins. (Bug#29627)
