Specify which games need vertex depth rounding instead of which ones don't.

Browse Source 
Vertex depth rounding is a not-fully-accurate hack, and most games are better off with the extra depth precision
of 24-bit Z than reducing it to a not-fully-accurate 16-bit. So let's only use it where necessary, like in Phantasy Star.

See issue #8187.
