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.
