[cairo] Remove hidden qt_draw_glyphs usage until qt provide public API version

[Oleg Romashin]

According to comment:
https://bugs.freedesktop.org/show_bug.cgi?id=29092#c5

we should add public API to Qt first, and then add usage in cairo.
I think we should go now  with default glyphs rendering fallback for
cairo-qt surface.

Here is the patch to remove hidden API usage
