Don't keep PMPrint* state separate from NSPrintInfo

When we need to use PMPrintSession, PMPrintSettings, and PMPageLayout,
get these directly from the NSPrintInfo when needed. This avoids us
needing to keep the settings in sync. The native dialogs can then only
rely on getting a pointer to NSPrintInfo (to be done in a future
commit).
