chore(cli): delete @expo/dev-server

[EvanBacon]

Why

• I tried this before but the logs endpoint was blocking it.
• I forked the dev server when I wrote the original expo/cli, been meaning to delete the original for a while. The duplicate code and indirection is making the new server features harder to implement.

How

• Copy/paste remaining code from @expo/dev-server in to @expo/cli.
• Delete @expo/dev-server.
• Drop unused /logs and json parser middleware.
• Drop logging mocks.
• Drop experimental Webpack native support.
• Drop legacy react-native middleware support (no longer needed since everything is versioned).

Test Plan

• Tests should keep passing.
• Need to do some actual runs since there aren't any e2e tests for various parts of dev-server.

Checklist

• Documentation is up to date to reflect these changes (eg: https://docs.expo.dev and README.md).
• Conforms with the Documentation Writing Style Guide
• This diff will work correctly for npx expo prebuild & EAS Build (eg: updated a module plugin).
