src: remove fixed-size GetHumanReadableProcessName

Remove the version of GetHumanReadableProcessName() that operates on a fixed-size buffer. The only remaining caller is Assert() which might get called in contexts where dynamically allocating memory isn't possible but as Assert() calls printf(), which also allocates memory when necessary, this commit is unlikely to make matters much worse.
