Don't commit libs in repo

[farfromrefug]

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
