Locale: move "translate application names" checkbox to formatting tab

Part of #15511

One more monster commit (sorry ...) concerning the Locale Kit:
* extracted new class BFormattingConventions from BCountry, which
manages the formatting conventions from a given locale and
allows to get/set the four different date/time formats supported
by ICU-locales as well as number and monetary formats
* overhauled the Locale preflet:
+ drop editing features for all formats, since I don't think
they do not make much sense to have in a prefs GUI - being
able to select from the existing locales should be good
enough. Please note that you can still change the formats
programmatically in an application.
+ renamed the 'Countries' tab to 'Formatting'
+ the locale formatting conventions list in the 'Formatting'
tab is now hierarchical for easier access (less scrolling)
+ fixed functionality of 'Revert' and 'Defaults' buttons
+ added support for using the month/day-names of your preferred
language during date formatting
* adjusted BLocale to ask BFormattingConventions for the current
formats when formatting dates and times and to offer 4
different format styles (full, long, medium and short).
* adjust all classes formatting dates/times to pick the
appropriate format style
* BLocaleRoster no longer directly archives/unarchives the
individual formatting conventions but delegates that to
BFormattingConventions

Next step of Locale Kit refactoring:
* BLocale now keeps language and country completely separate and
mixes the formatting conventions into the current language's locale
when formatting dates and times (needs to be done for number- and
currency-formatting, too, since the digits may not be in the
preferred language)
* optimized fetching of the flag icons such that they are all loaded
in one go (by the locale roster) - this alone speeds up the Locale
preflet considerably
* worked on fixing the language confusion in the Locale preflet
* fixed a couple of bugs in the Locale preflet that would lead to
illegal characters being displayed in the date-subpart menus

Set the radiobuttons depending on the currency symbol position.

Preliminary support for adjusting the money format in the locale preflet :
* API for formatting a number and recovering the field positions
* Some changes in the preflet to display the formatted number and start filling in the fields.

* Move the locale-related stuff away from BCountry to BLocale.
* Remove the be_locale global object and go through the be_locale_roster instead
* Rework the storage of data for the be_locale_roster, since BLocale already holds a BCountry and a BLanguage.

* Rename TimeFormatSettingsView to FormatSettingsView, since it also provides number and currency formatting.
