fix(eslint-plugin): [no-implied-eval] don't report when Function is imported

[soobing]

Hi, first PR in typescript-eslint. 😊

This PR is from #2338 issue.
When import named Function,

import { Function } from "@aws-cdk/aws-lambda";

new Function(scope, "MyLambdaFunction", { /* ... */ });

{
  "rules": {
    "@typescript-eslint/no-implied-eval": "error"
  }
}

the following error is logged:

error    Implied eval. Do not use the Function constructor to create functions  @typescript-eslint/no-implied-eval
