feat: Add two generation config flags to raise exceptions

[robertschweizer]

raise_on_error_status raises a httpx.HTTPStatusError on all error response codes without decoding. This can later be improved to add an exception that includes the decoded content, or to even raise different exception types for each response code (see https://github.com/openapi-generators/openapi-python-client/pull/736#issuecomment-1493038758).

raise_on_unexpected_status is identical to the existing Client.raise_on_unexpected_status runtime setting, but leads to better return type annotations.

Closes https://github.com/openapi-generators/openapi-python-client/issues/491

This is a rework of https://github.com/openapi-generators/openapi-python-client/pull/736, with the main intention of reducing the generated sync and asyncio functions' return type annotations to documented successful responses.

Includes the commits from #742, which should be merged first.
