Separate uilib-native package

[ethanshar]

Description

Decouple uilib-native (lib) components from uilib src components
This is in order to support mini-bundles and eventually code push
The fact that uilib-native's native part is in one package but the JS components is in anohter (react-native-ui-lib) was causing an issue
This PR separates the two without a breaking change to the community (they won't be required to install uilib-native package)

Changelog

Decouple uilib's native components from its JS library

Additional info

@ethanshar, this change does potentially break public users that use our native components, an error will appear only when such component is used (tested with the fix below*). This happens because they do not have the native-uilib package installed.
Moreover, in our project the Android build is failing: java.lang.StackOverflowError (no error message) not sure what's exactly is the issue there, however it works on master (I have a general issue with iOS ATM).

• Our native components are broken ATM - PR to fix it: Move from npmignore to files in order to fix the native components packaging #3319

@M-i-k-e-l
I merged your other PR #3319 and merge it to this PR
Both Android and iOS builds are working for me locally in this PR, can you double check?
I will try installing this version on a random project to see the issue you talked about
