Avoid fz_font pulling harfbuzz in.
We store an hb_font in every font, and currently have fz_drop_font
know to call harfbuzz to destroy it. This causes harfbuzz to be
included even in builds that never use it.
We improve this situation by storing both an hb_font, and a
function pointer to destroy it within fz_font. This costs us
an extra pointer per fz_font, but solves the problem.
