[css-ui] Add support for caret-color property

     The `properties' dict can be used to access a property's parameters in
     jinja2 templates (i.e. setter, getter, initial, type_name)

Since this is only for a single property, it's better to not have a macro and
just write this out in StyleBuilderCustom.cpp

Ok I'll move it.
Anyway, as I said it's supposed that new color properties follow the same
pattern,
but we can create a macro later if needed.

   if (!parentMap)
     return;
