update js-client api (migrate to TS)

Summary:
JS/TS api:
- migrate to TS
- some refactoring (get rid of bridge, make client abstract)

Implementation isn't full yet, things to be implemented:
- let plugins connect on init command from Flipper
- implement Responder

Further plans:
- make fully compatible with react-native api without breaking changes
