Don't commit libs in repo

The github repo of the runtime is getting huge and thus hard to maintain. Even more if we think about releasing more flavors (wasm, Intl...)
Maybe we could think about publishing the libs as github releases with tags instead.
Then we would pull the correct one when installing the @nativescript/android. Or maybe even during prepare.
Another benefit(?) would be a smaller npm package.
All could be prepared/release through github action

首先审查哪些库已提交到仓库，以及如何安装和准备 @nativescript/android。检查现有的 release 流程和 GitHub Actions 配置（如果有）。完成的标准是达成一致并实现完整的 release 和安装流程，移除已提交的库，同时获取正确的 flavor 并缩小 package。
