CMake: propagate include flag for harfbuzz on Windows

Pango >=1.44.1 changed the way harfbuzz is included
xref: https://github.com/GNOME/pango/commit/a7b17aa2

This is not required on *nix because the PkgConfig CMake module
already takes care of this. For example, on Ubuntu it adds:
-I/usr/include/harbuzz to PangoCairo_CFLAGS
