Remove the use of OwnedPtrDeleter in HarfBuzzFace.

It's hard to mechanically replace specializations of OwnedPtrDeleter<T>
to std::unique_ptr equivalents. Therefore, they are converted to
std::unique_ptr manually.

The specializations in HarfBuzzFace.h are only used from
HarfBuzzFace.cpp, so the new deleters are added in .cpp file. New
typedefs are created so people can always use std::unique_ptr with a
correct deleter.
