Update TestDataSource (chrome://test/) to be able to load chai.js from
//third_party/.

Change chai_assert.js to import chai.js and add assertArrayEquals()
because it used in several tests in WebUI and Files app.

Nits addressed for array_data_model_test.js:
- Add type check.
- Remove "#export" markup.
- Use Object.assign() to export test functions to global scope.
