QCupsPrinterSupport: avoid network browse when reading default printer

staticDefaultPrintDeviceId() used cupsGetDests(), which enumerates all
destinations, including network printers discovered via DNS-SD. That
discovery triggers a blocking avahi browse, so just reading the default
printer's id could take seconds depending on the network.

Use cupsGetNamedDest(CUPS_HTTP_DEFAULT, nullptr, nullptr) instead: a NULL
name returns only the default destination, resolved locally without any
DNS-SD browse. This cut the QPrinter constructor from 250ms to 54ms here.
