Reviewed by Kent Tamura.

Source/WebCore:

We are moving calendar picker PagePopupClient to WebKit layer so ports
can use their platform native chooser UI if they have one.
DateTimeChooser, DateTimeChooserClient etc. will be reused when we
implement the week picker and month picker.

No new tests. No behavior change. Covered by existing calendar picker tests.
