ARB + ICU json frameworks | android + iOS locales output directories

[joustrich]

Overview

• New arb framework for the json format
• New icu framework for the json format (was previously just format json_icu, which still works but logs a warning and is marked deprecated)
• New androidLocales to match iosLocales
• New androidLocalesOutDir and iosLocalesOutDir for outputting android/iOS files to different root directories

Context

See ditto-app PR for corresponding backend and documentation changes

Test Plan

Testing successfully completed in local via:

• Make sure you have a few variants set up with corresponding locales
• Make sure your config has the following (see my example config below)
  • all variants
  • android, ios-strings, ios-stringsdict, json (w/ framework arb) formats
  • iosLocales and androidLocales specified for all of your variants
  • outDir, iosLocalesOutDir and androidLocalesOutDir all specified to separate web/iOS/android outputs
• Once you have the config set up against your projects, run pull (or yarn sync if running from this project)
• You should see your ARB json files in the outDir, iOS files in the appropriate structure in your iosLocalesOurDir and android files in the appropriate structure in androidLocalesOutDir.

  - id: "jao-test"

there is one regional bug for arb, but other than that it's good
