[go-experimental] Fix nullable support (#5414)

* Fix nullable support in go-experimental client

* Fix support for models with parents and container fields

* Make sure that oneOf interfaces serialize properly even if they're required (non-pointers) on other models

* Spaces => tabs

* Regenerate samples

* Make some methods of nullables pointer-receivers, add tests

* Improve the Get/Set logic to make usage more convenient

* Address review
