Mike Kaganski 7b2ea917ce Optimize JsonToPropertyValues a bit
1. Make it take string view: helps to avoid extra string allocation
e.g. in desktop::jsonToPropertyValuesVector, and will help more,
when C++26 stringstream ctor taking string view is available.

2. Factor out a function taking boost::property_tree::ptree, making
implementation simpler for [][]com.sun.star.beans.PropertyValue and
[]com.sun.star.beans.PropertyValue, without writing a child node to
a JSON string, and parsing it again.
