refactor: use resolvePackageData in requireResolveFromRootWithFallback #12712

Description

This PR changes requireResolveFromRootWithFallback to use resolvePackageData instead of resolve.sync.

This function was introduced by ddfcbce and changed by #3988 and #10812.

Previously, this function was using require.resolve.paths and was passing this to resolve.sync and require.resolve. Now this function simply passes root and __dirname. IIUC this behaves same because

  • require.resolve.paths returns the value of NODE_MODULES_PATHS in this all together section
  • require.resolve uses paths option as a starting point for the module resolution algorithm. Also require.resolve always uses GLOBAL_FOLDERS. In other words, require.resolve will use paths.flatMap(p => NODE_MODULES_PATHS(p)) as candidates.

So passing root to paths option of require.resolve is same with passing createRequire(root).resolve.paths to paths option.

I tested this PR by the way written in #2612 and #10812.
