[python][Feat] Deserialize error responses (#17038)

* refactor: Clean up _response_types_map formatting

It matches black's behavior of having trailing commas now.

* test: Add test to reproduce #16967

* fix: deserialize responses even if no returnType

Closes #16967

* refactor: Simplify ApiException subclasses

* refactor: Move exception subtype choice to ApiException

* feat: Deserialize error responses and add to exceptions

* test: Add for error responses with model
