Canon and HP driver profiles for quick actions

Canon: CNColorMode color/mono, CNDuplex, PageSize=Letter. HP: HPColorAsGray or
HPColorMode; duplex and Letter from the generic profile. Profiles can mark an action
unavailable with a reason (Canon department IDs, HP accounting codes). Use Letter
Paper only says Fit to Nearest Size when the profile sets a fit option. Offline tests
sweep every Canon and HP PPD found in CUPSKIT_PPD_DIRS or /Library/Printers/PPDs.
