M10: every paper size reaches the printer, from the dialog and doc_print (#3752)

A CUPS job that names no paper gets the queue's PPD default (A4 on the
reporter's Xerox queue), whatever the sheets were laid out on. Two gaps
remained after #1583:

- cups_media had no name for 13 of the 21 PAPERS sizes (A6, ARCH A-E1,
  ANSI C-E, A0-A2), so the Print dialog sent no media for them. They now
  use PWG 5101.1 names (the IANA-registered na_arch-e1_30x42in for ARCH
  E1), which carry their dimensions: CUPS feeds the driver's size of those
  dimensions whatever the driver calls it, and driverless IPP printers use
  them natively. Checked with cupsfilter against a synthetic PPD whose
  sizes use vendor keywords (ARCHD, AnsiD, A0...): each name produced its
  size's bounding box. The 8 sizes that already worked keep their PPD
  keywords.
- doc_print to a printer (CLI run, MCP) sent no paper at all. It now
  resolves the paper to its PAPERS index and sends the same media option
  as the dialog, after the driver options. The job is built in spool_job
  so it can be tested without printing.

print::media_option is the one place both get the option from. Both new
tests were seen failing without the fix. The macOS tray half of #3752
(Auto Select instead of the PPD's default tray) is a craft-print change.
