Starting with Xcode 14, bitcode is no longer required for watchOS and tvOS applications, and the App Store no longer accepts bitcode submissions from Xcode 14.

Most bitcode usage was removed in flutter/engine#36596. Also remove strip_bitcode logic. See flutter/engine#36496

# When we stop building with bitcode enabled, this template and the
# strip_bitcode.py script can be deleted and users can call copy() instead.
