Fix a few issues with the C generator (part 3) (#20269)

* [C] Clear the response code from previous api calls

Before making an api call, reset apiClient->response_code to zero. That
will protect us from checking stale values if the curl request fails.

* [C] Check that string arguments are not null

Check early on that the arguments are not null, to prevent crashes on
strdup() calls.

* [C] Don't attempt to fill in a type with error info

Check if the api call returned an error before attempting to parse the
reply as the expected type.

* [C] Handle binary and integer return types

* [C] Update test schemas with binary and integer return types

* Update samples
