reject-chromeutils-import

While ChromeUtils.import supports the fallback to ESMified module, in-tree files should use ChromeUtils.importESModule for ESMified modules.

Examples of incorrect code for this rule:

ChromeUtils.import("resource://gre/modules/AppConstants.jsm");

ChromeUtils.defineModuleGetter(
  obj, "AppConstants", "resource://gre/modules/AppConstants.jsm");
XPCOMUtils.defineLazyModuleGetters(
  obj, { AppConstants: "resource://gre/modules/AppConstants.jsm" });

Examples of correct code for this rule:

ChromeUtils.importESModule("resource://gre/modules/AppConstants.sys.mjs");

ChromeUtils.defineESModuleGetters(
  obj, { AppConstants: "resource://gre/modules/AppConstants.sys.mjs" });
