tdf#126700 allow replacing the default documents

Per default, a document opened by a user action will always open
in a new frame. For tdf#83722, this behaviour was extended to
documents created from templates.

But this currently also affects the default factory templates, if
these are replaced by a config setting with a real template, which
was not intentional.

So this patch introduces a new MediaDescriptor property, which
allows to mark a document as replaceable and automatically sets
it for factory default documents. If this property is set to true,
a document just acts as a placeholder while it's unmodified. I.e.
the next opened document from its frame will close and replace it.

For this backport the documentation in MediaDescriptor.idl is
dropped, so people won't rely on this as a feature before 7.0.
