Deprecate QLocale::Language entries that no locale data relates to

These are languages for which CLDR does not even recognize the claimed
language code (three-letter codes except for bh = Bihari, which might
be an old name for bho = Bhojpuri, which CLDR does give, but provides
no locale data using it).

[ChangeLog][QtCore][QLocale::Language] Many obsolete language names
are now deprecated in preparation for removal at Qt 6.0. No data has
been available for any locale using these languages since CLDR v29 (at
least; Qt now uses v37).

Task-number: QTBUG-84669
Pick-to: 5.15 5.15.2
