Add `data-test-id` prop to `TextField` component (#13973)

The `data-test-id` prop has been added to `TextField`. This prop allows
selecting this component more easily from e2e and unit tests. This is
required for a subsequent PR that includes a text field that cannot be
selected for by placeholder or contents or label (any of which would
have been preferable).
