Bundled build with freetype doesn't actually work

[waywardmonkeys]

When we build with --features bundled, we need to add this to the harfbuzz-sys/build.rs:

if cfg!(feature = "freetype") {
    cfg.define("HAVE_FREETYPE", "1");
}

Unfortunately, this will fail as we need to set up additional build flags for the build to find freetype (and this is even more unfriendly on Windows).

This gets a bit annoying when freetype is in the default features ...

Maybe for now we can say that Windows only supports directwrite and not freetype?

Let me look at this tomorrow and see if I remember what direction I was thinking. I suspect that not having these as default features would be good.

(Since I don’t think Servo actually used the platform stuff…)
