Fixes delink failures in Action.obj and ActSequence.obj.
Some missing data types have been added to each corresponding header
file, and entries have been added to the symbol table to fix errors from
undefined types. The mangling script has also been amended to handle
method pointers as they're currently imported into Ghidra (which are
missing the calling convention, and likely behind a typedef).
In the decompilation proper, the SaveData "Vs" methods have been renamed
to "Unused" methods (they have nothing to do with multiplayer). Other
symbols in the symbol table have also been updated, particularly
relating to CActSequence (previously known as Director).
The Yakuza 1 and 2 rereleases on the Wii U export function symbols,
preserving their names, and some debug data was also available in a PS2
release, providing some struct definitions. These have been used to
rename analogous classes, functions, and member variables to the same
names used by Smilebit, plus a more general imitation of their naming
and typing conventions (i.e. Win32 style).
