auto-detect composer language from keyboard

adds a new expo-keyboard-language native module that reads the current
keyboard language on iOS (via first responder's textInputMode) and
Android (via InputMethodManager). iOS also gets real-time updates when
the keyboard language changes.

users opt in via Settings > Languages > "Automatically detect post
language from keyboard" (native only, marked experimental). when
enabled, the composer language tracks the keyboard language. users can
override per-session by selecting a language manually, and re-enable
auto mode via the "Automatic" item in the language menu.
