Moving CUPS printers files from c/b/r/settings/printing_page to
c/b/r/settings/chromeos/os_printing_page, and deleting CUPS printers
link row from browser settings printing page, since it is only shown
when showing the OS settings.

Also fixing the getEulaUrlGetsCalledOnModelChange test, as it always
fails for optimize_webui=false before this CL. This appears to have
never been detected due to https://crbug.com/1003483, which disabled
all OS settings browser tests on debug builds.
