In the first commit we removed the
createImportExpressionsrequirements for the import phase proposal.In the 2rd and 3rd commits we added more comments handling test cases and fixed a new bug surfaced from the new tests
In the 4th commit we add trailing comma handling to the ImportExpression such that
experimental_preserveFormatcan preserve the trailing comma in dynamic importIn the 5th commit we simplified the import phase comment handling.
