[Reland] Add a workflow to release Android binaries (pytorch#110976)

This adds 2 jobs to build PyTorch Android with and without lite interpreter: * Keep the list of currently supported ABI armeabi-v7a, arm64-v8a, x86, x86_64 * Pass all the test on emulator * Run an the test app on emulator and my Android phone `arm64-v8a` without any issue ![Screenshot_20231010-114453](https://github.com/pytorch/pytorch/assets/475357/57e12188-1675-44d2-a259-9f9577578590) * Run on AWS https://us-west-2.console.aws.amazon.com/devicefarm/home#/mobile/projects/b531574a-fb82-40ae-b687-8f0b81341ae0/runs/5fce6818-628a-4099-9aab-23e91a212076 Pull Request resolved: pytorch#110976 Approved by: https://github.com/atalman
