Refactor MavenImportListener in MavenUtils

The importFinished method in MavenImportListener has been modified to receive two additional parameters: importedProjects and newModules. Additionally, unnecessary import lines for javaApi and javaRuntime were removed from MavenUtils.kt. This refinement provides more information during the import finish event for further handling.

(cherry picked from commit d62be21)
