tdf#139205: Keep hierarchical structure of localized default styles in Calc

The default cell styles (when creating a new Calc document), as returned by orcus
parsing, are built-in English names, as defined in sc/res/xml/styles.xml. These
names can be localized. On non-English UI, all these (localized) styles names
will be forced to use the localized "Default" as their parent because there is
no such non-localized parents in the localized style tree on UI.

In this patch, I added SC_DLLPUBLIC to ScStyleNameConversion::ProgrammaticToDisplayName,
then used this function to convert the parent style name to the (localized) UI name.
