Subject: [PATCH] Android CI: set up NDK via local.properties (#30259)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/30259

Before side-by-side NDK is supported by the Circle CI image, pending https://github.com/facebook/react-native/pull/29050 & https://github.com/facebook/react-native/pull/29987, this local.properties file forces Gradle to use the specified SDK/NDK path. We do this internally at FB CI as well.

This addresses the following failure:
https://app.circleci.com/pipelines/github/facebook/react-native/6851/workflows/9fd91d5d-3f05-4521-93fc-95abd5c84227/jobs/173735

Also, this fixed bad src copy for Buck-building: `//packages/react-native-codegen:setup_cli`
