Get rid of QGlyphLayout::advances_y
...and thus consume 4 bytes less per glyph and increase the performance a bit.
It seems, the only CTFontGetAdvancesForGlyphs() returns both x and y
advances, though y advances are always equal to 0 for horizontal
orientation and x advances are always equal to 0 for vertical orientation.
Also, rename `advances_x` to `advances` for consistency
and declare QGlyphLayout's data size in a single place.
