chore(lint): add eslint-plugin-eslint-plugin internally and fix viola…

…tions

This PR adds [eslint-plugin-eslint-plugin](https://github.com/not-an-aardvark/eslint-plugin-eslint-plugin) (a popular plugin for linting eslint plugins), enables relevant rules from it, and fixes violations.

The primary changes included are:
1. Adds missing rule schemas ([require-meta-schema](https://github.com/not-an-aardvark/eslint-plugin-eslint-plugin/blob/master/docs/rules/require-meta-schema.md)). Note that `schema: []` is added to enforce when a rule should have no schema.
2. Adds missing rule `type` property to `no-unused-modules` rule ([require-meta-type](https://github.com/not-an-aardvark/eslint-plugin-eslint-plugin/blob/master/docs/rules/require-meta-type.md)).
3. Removes duplicate test cases ([no-identical-tests](https://github.com/not-an-aardvark/eslint-plugin-eslint-plugin/blob/master/docs/rules/no-identical-tests.md)).
4. Adds missing test case `output` assertions ([consistent-output](https://github.com/not-an-aardvark/eslint-plugin-eslint-plugin/blob/master/docs/rules/consistent-output.md)).
5. Switches some test cases to use the string shorthand ([test-case-shorthand-strings](https://github.com/not-an-aardvark/eslint-plugin-eslint-plugin/blob/master/docs/rules/test-case-shorthand-strings.md)).
