Fix some issues and streamline regeneration process: - A few glitches (like duplicate language symbols, wrong Windows language ids etc) were fixed. - Scripts were added to allow to regenerate the list of supported locales from the list of known Windows locales. - Version info when language symbols became available was added to the documentation of the language symbol enum. - Synonyms are no longer hard-coded in the script genlang.py. See #23453. Closes #23437.
