[csharp][generichost] Fix model accessor (#15918)

* removed redundant properties

* removed commneted code

* fixed oneof anyof serialization

* restored discriminator as a model property

* added manual sample, removed need for new discriminator property

* minor pipeline change

* renamed manual test solution

* fixed model accessor

* used visibility option

* resolved conflicts

* build samples

* resolved conflicts

* resolved conflicts

* resolved conflicts

* resolved conflicts

* added a comment
