Fix wrong overhang display for gstring compositions (Bug#12364).

* xdisp.c (right_overwritten, right_overwriting): Also handle gstring
composition cases (Bug#12364).

* xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
overhang of succeeding glyphs overlapping box cursor.

* w32term.c (x_draw_glyph_string): Likewise.
