sw content controls: add ODT export

Wrap the text portions inside the content control in a
<loext:content-control> XML element. Also map the (so far) single UNO
property of it to <loext:content-control
loext:showing-place-holder="...">.

This is just initial export for inline text content controls, more
properties are to be added in follow-up commits.
