feat(metro-config): disable require rename

[EvanBacon]

Why

• Speed up transformation and make output development bundles nominally easier to read by leaving the require name as-is.
• The upstream PR is stuck feat: add unstable_renameRequire to allow disabling the require rename transform facebook/metro#1230

How

• Fork the js file wrapping for converting modules to iife, and add an extra option to disable converting require to _$$_REQUIRE. This legacy behavior can be re-enabled by adding EXPO_METRO_RENAME_REQUIRES=1.

Test Plan

• Tests will continue working, we may want to add a smaller test.

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).
