Merge branch 'qlocale_tatar' into 'mer-stable'

[qtbase] QLocale data regenerated with initial Tatar locale support. Fixes MER#1707

The Tatar locale data is taken from the recent CLDR tag (v30.0.2), but all other locales kept the same version (v23.1). The language data is inserted in between, so it moves a lot of other locale data, which increases the diff.
