Adding more testcases to :placeholder-shown class.

Adding more testcases to :placeholder-shown class.

As per the spec
https://html.spec.whatwg.org/multipage/forms.html#input-type-attr-summary
input types date, time, month, week, datetime-local, file, image, reset etc
should ignore placeholder attribute and in-turn should not affect placeholder-shown state.
Adding testcases for the same.

    search, date, month, week, time, datetime-local, file, image, reset
