pvg: add option to configure it out

... and also to require it (--enable-pvg).  While at it, unify the dependency()
call for pvg and metal, which simplifies the logic a bit.

Note that all other Apple frameworks are either required or always-present,
therefore do not add them to the summary in the same way as PVG.
