Remove Mocha unit test runner

[tylersmalley]

We have long since preferred using Jest for unit tests within the Kibana repository, and from what I can tell there is no reason all existing Mocha tests can not be migrated to Jest. This meta issue will serve to track the migration of those tests and the cleanup to follow.

• Convert @elastic/datemath tests to Jest
• Move Jest tests outside __tests__ directories
  find src x-pack packages -iname \*.test.ts -o -iname \*.test.js | fgrep __tests__
• Convert @kbn/es-archiver tests to Jest
• Remove test runner ci integration
