harfbuzz: revise build and bindings

Browse Source 
More recent versions of harfbuzz conveniently generate harfbuzz.cc
which has the full list of source files, so point our build to
that instead of chasing the evolving list of files: much easier!

Fixup some of the predefined symbols, and include opentype functions
in bindings.h so that we can pick those up in the bindgen output.
