sw content controls: add ODT import

Map

<loext:content-control loext:showing-place-holder="...">

to com.sun.star.text.ContentControl and set its ShowingPlaceHolder
property based on the XML attribute.

This requires moving XMLImpSpanContext_Impl to txtparai.hxx, otherwise
XMLContentControlContext would have to be in txtparai.cxx, which is
already large.

(cherry picked from commit d1649e5d38b51cd422302e566719a2c5aff42b2f)
