[bare-expo][ncl] Add native-component-list to bare-expo (#6868)

# Why

Make it easier to test things on both workflows at the same time.

# How

- Added `native-component-list` as a dependency

[bare-expo][ncl] Add native-component-list to bare-expo (#6868)

# Why

Make it easier to test things on both workflows at the same time.

# How

- Added `native-component-list` as a dependency of `bare-expo`.
- Updated `app.json` config for web as now we need to tell babel to transpile files from NCL.
- Resolved some issues caused by the fact that NCL was intended for use in managed workflow.
- Added new bottom tab bar navigator for switching between TestSuite, Expo APIs and Expo Components.
- Removed `standalone-ncl` app - it's useless now.

# Test Plan

- [x] Test bare-expo on mobile
- [x] Test bare-expo on web
- [x] Test native-component-list on mobile
- [x] CI tests are passing

I haven't tested whether every NCL screen works inside BareExpo, hopefully we will be fixing them separately once we use those screens.

# Demo


# Proposals for improvements in the future

- Create `managed-expo` app that is actually the same as `bare-expo` but for managed workflow. That would make it really easy to debug every thing in both workflow at once.
- Add the possibility to exclude `native-component-list` when running on the CI - with NCL it takes a bit more time to load the page.
- I noticed the first tests (Basic) are taking much more time than subsequent ones and I guess it's because the first `page.goto` call triggers webpack to start bundling the app and until then we don't receive any response. Maybe we should open that page at the root path before running tests and give it as much time as it needs to and thus prevent timeouts in the first tests ��
