LibDebug+HackStudio: Fix crashes relating to debugger variable preview

For one, viewing a variable who's type contained a subprogram will
no longer crash HackStudio. Additionally, the variable view will
handle invalid enum values gracefully now, fixing another crash.
Finally, deeply nested (nest count > 1) structures will have their
memory addresses properly set, fixing the final crash I found.
