[cmake] feat: FFmpeg CI, allow 16kb android builds, update translations for transifex (#2543)

Uses an FFmpeg CI for Android and Windows, also available for Linux. Saves compile time on Linux and is more consistent on Windows/Android.

Also, updates VVL and FFmpeg to allow for a fully 16kb-compliant Android build. Bonus: APK size is down 30%

Updated all localization files for Transifex while I was at it

TODO for future: Android 8.0 with vp9_vulkan et al.

+When creating/improving translations, please keep in mind:
+
+- You are responsible for providing accurate translations that do NOT contain illicit content or messages,
+- Many of our developers do not speak the languages you may be translating, so will only be able to help with confusions about the source language,
+- And bad-faith translations or attempts to insert illicit content may result in an immediate removal of access.
