refactor(select): rename the checked attribute to selected on option

BREAKING CHANGES:

The Option component’s `checked` attribute has been renamed to
`selected` in order to select an option. This is to the follow the MDN
spec for a select option:
https://developer.mozilla.org/en-US/docs/Web/HTML/Element/option

If a `ngModel` is added to the Select component the value of the
`ngModel` will take precedence over the `selected` attribute.
