editengine-columns: ODF support [API CHANGE]

This uses existing ODF markup, as used by Writer's text frame:
style::columns child element of style:graphic-properties, its
fo:column-count and fo:column-gap attributes. No ODF extension
is required.

Since currently only columns with same width and spacing are
implemented, without additional settings, style:column child
elements are exported, but ignored on import.

This adds new property to css::drawing::TextProperties service:
TextColumns (of type css::text::XTextColumns).
