sw content control, date: allow selecting via the keyboard

It was not possible to select the date of a date content control via
keyboard.

This meant only the mouse handling codepath needed implementing, but it
broke accessibility.

SwContentControl::ShouldOpenPopup() already knows how to handle
dropdowns via the keyboard, extend that to handle date pickers as well.

The appearing vcl Calendar / GtkCalendar appears to support keyboard
navigation already.
