tdf#121842 sw: add hyperlinks to toxmarks in ToC/User-Defined Index

The toxmark is identified by the type of index, the name of the index
type (only for user-defined; there is only one ToC type), the text
(either text:string-value or text content of the toxmark),
and a counter to distinguish marks with the same text.

Both text and type name can contain arbitrary characters so use U+0019
control character as separator.

Links look like: #1%19text%19Utypename|toxmark
