@react-native/babel-preset imports from react-native not deferred (lazy requires)

[stevoland]

Description

Failing test repro

The expected behaviour of @react-native/babel-preset is to defer the evaluation of a subset of react-native modules until the scope in which they are first referenced: https://github.com/facebook/react-native/blob/main/packages/react-native-babel-preset/src/configs/main.js#L76

This is no longer happening (as @babel/plugin-transform-modules-commonjs passes the source string to the lazy callback, not the expected import specifier). See test 2.

Steps to reproduce

git clone git@github.com:stevoland/RNTest.git
git checkout lazy-imports-repro
yarn
yarn test babel.test
