migrate to boost::gettext

* all .ui files go from <interface> to <interface domain="MODULE"> e.g. vcl
* all .src files go away and the english source strings folded into the .hrc as NC_("context", "source string")
* ResMgr is dropped in favour of std::locale imbued by boost::locale::generator pointed at matching
  MODULE .mo files
* UIConfig translations are folded into the module .mo, so e.g. UIConfig_cui
  goes from l10n target to normal one, so the res/lang.zips of UI files go away
* translation via Translation::get(hrc-define-key, imbued-std::locale)
* python can now be translated with its inbuilt gettext support (we keep the name strings.hrc there
  to keep finding the .hrc file uniform) so magic numbers can go away there
* java and starbasic components can be translated via the pre-existing css.resource.StringResourceWithLocation
  mechanism
* en-US res files go away, their strings are now the .hrc keys in the source code
* remaining .res files are replaced by .mo files
* in .res/.ui-lang-zip files, the old scheme missing translations of strings
  results in inserting the english original so something can be found, now the
  standard fallback of using the english original from the source key is used, so
  partial translations shrink dramatically in size
* extract .hrc strings with hrcex which backs onto
   xgettext -C --add-comments --keyword=NC_:1c,2 --from-code=UTF-8 --no-wrap
* extract .ui strings with uiex which backs onto
   xgettext --add-comments --no-wrap
* qtz for gettext translations is generated at runtime as ascii-ified crc32 of
   content + "|" + msgid
* [API CHANGE] remove deprecated binary .res resouce loader related uno apis
      com::sun::star::resource::OfficeResourceLoader
      com::sun::star::resource::XResourceBundleLoader
      com::sun::star::resource::XResourceBundle
    when translating strings via uno apis
      com.sun.star.resource.StringResourceWithLocation
    can continue to be used
