sw content controls, plain text: add doc model & UNO API

OOXML's <w:sdt> with <w:text> describes a plain text content control. We
are currently mapping this to fields, and then on export it's possible
to map this to FORMTEXT fields. The trouble is that our doc model could
not differentiate between content controls and fields for non-formatted
form text, so the exporter can't do the opposite of import.

This has the benefit that input fields do a reasonable job of providing
the feature set of plain text content controls, but it has the downside
that we map two OOXML features to a single Writer concept, loosing
formatting.

Fix this by introducing a dedicated "plain text" content control type,
which can be used for OOXML's <w:sdt> with <w:text>, and keep using the
input field only for OOXML fields.

This commit just adds the document model & UNO API, follow-up commits
will add the remaining functionality.
