📚 Description

This PR improves Nitropack v2 externals tracker by analyzing dependency tree between packages in multi phases:

• Identify single versioned packages and multi versioned packages with their (versionined) parents
• Wrtie single versioned packages in parallel directly to node_modules
• For each multi versioned package
  • Sort it's versions based on 1) no parents for hoisting 2) newer to older version
  • For each version
    • Write it to node_modules/.nitro/name@version
    • For each multi version parent, link to node_modules/.nitro/mv_parent}/node_modules/{name}
    • For each single version parent, link to node_modules/{sv_parent}/node_modules/{name}

This solves concurrency issue, improves performance and handling hoisting for hoisted versions (tested against nice reproduction provided by @itpropro against "@azure/app-configuration": "^1.3.1" + "@azure/search-documents": "^11.3.1" + "@azure/identity": "^3.1.3" with conflicting @azure/core-tracing (1.0.1/1.0.0-preview.13)
