* Configurable opts for babel-preset-env + babel-plugin-transform-runtime This adds `preset-env` and `transform-runtime` options to the `next/babel` Babel preset, which are then passed through to those presets and transforms. This allows configuration to keep next.js from the default 'maximum' transform, and instead use built-in implementations of globals, classes, async, and other commonly-supported features. Fixes #2989 * Use spread notation instead of Object.assign
