Add build-all-manpages.sh for multi-language manpage generation

Orchestrates manpage builds for 19 languages: downloads per-language
tldr archives, copies l10n locales into coreutils, generates manpages
with the appropriate LANG setting, and invokes build-manpages.sh with
English tldr fallback for each language.
