Behdad Esfahbod 9cc9ffe352 [util/draw] If HB_DRAW is not set, choose depending on cairo version

on cairo version

Khaled Hosny 74ebfc646a [meson] Update cairo subproject
Update to the current master branch so that is has
cairo_user_font_face_set_render_color_glyph_func().

I had to disable optimized builds on win[32|64] crossbuild setups
because they are now broken in the CI (something about cairo defining
_FORTIFY_SOURCE for optimized builds that MingW does not like).

Khaled Hosny cf28821337 [meson] fix building with Cairo subproject
We can’t pass internal (subproject) dependency to cpp.has_function(), so
we manually hard-code the result.

Behdad Esfahbod 542f8269cb [util/draw/ft] Use hb-draw for font-funcs=ft as well
If cairo is >= 1.17.5.

This essentially breaks emoji and bitmap fonts for now.

Is automatically enabled if cairo is recent enough, and font-funcs are
not 'ft'.

Uses cairo-user-font backend internally.

Behdad Esfahbod 1740916ede [draw] Remove check for no-op
This is unnecessary overhead. Up to rasterizers to handle this.  Plus,
this throws off point-numbers in uses that rely on it.

Disabled one test that broke with this.
