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.
