libharfbuzz technical debt

Callable exports - 35 callable NIDs match the public 3.20 catalogue and the selected export metadata from an older libharfbuzz image and a later libSceVshHarfBuzz image (SHA-256 25af97e02c1fa8d318ff3697eb8a79057ee9b8c5e5e4ec321f25114aceb05628). The later image has a different module and library identity; matching NIDs do not establish forwarding or equivalent behavior. The version labels are not authenticated. Prototypes and behavior are unverified; these declarations throw through NotImplemented_nid_no_patch and implement no runtime functionality.
