build: Replace Codelyzer and TSLint with Angular ESLint

Migrate from the deprecated TSLint to Angluar ESLint. Also fix current
linting issues in the code, in particular:

- Use strict equals operators (=== and !==)
- Remove empty lifecycle methods (mostly ngOnInit)
- Output bindings including aliases should not be named as standard dom
  events (submit)
- Async pipe results should not be negated
