Add armv7 support to create_ios_framework script (#4942)
Add armv7 support to create_ios_framework script (#4942)

This adds support for --armv7-out-dir and renames --device-out-dir to
--arm64-out-dir for clarity. It preserves --device-out-dir as a fallback
until the bot recipe has been updated to use --arm64-out-dir.
