Add new partial translations for a few locales

[AMoo-Miki]

Description

Add new partial translations for:

• zh-TW
• zh-CN
• tr-TR
• pt-PT
• pt-BR
• ko-KR
• ja-JP
• it-IT
• id-ID
• fr-FR
• fr-CA
• es-ES
• es-419
• de-DE

These are incomplete and the formats mimick en. Now that Intl is matured enough, we probably should drop the requirement for formats.
