Clean up SkFontHost_Mac ownership.

This clarifies ownership rules throughout SkFontHost_Mac.cpp, as well as
tidying up various bits of code. Clarifying ownership means replacing 
AutoCFRelease with UniqueCFRef which is based on std::unique_ptr. Most of
the cleanup is removing now dead code and properly indenting.
