Describe the new feature:
Follow up of #37262
I believe these are all the required items to implement import map in script_module.rs

• create an import map parse result
  • sorting and normalizing a module specifier map
  • sorting and normalizing scopes
  • normalizing a module integrity map
• register an import map
• resolving a URL-like module specifier
• resolve an imports match
• resolve a module specifier: We already have the method here, but we need to expand it.
  • referringscript
• Include import-map in include.ini
