fix(event_handler): allow responses and metadata when using Router

[rubenfonseca]

Issue number: #3506

Summary

Changes

Please provide a summary of what's being changed

Some of the new additions related to OpenAPI support added non-hashable elements to the route key when using the built-in Router.
This made the code crash. With this change, we convert all those new parameters into hashable equivalents.

User experience

Please share what the user experience looks like before and after this change

The following code now works:

router = Router()

@router.put("/example-resource", responses={200: {"description": "Custom response"}}, tags=["example"])
def handler():
    pass

app = APIGatewayRestResolver(enable_validation=True)
app.include_router(router)

schema = app.get_openapi_schema()
put = schema.paths["/example-resource"].put
assert len(put.tags) == 1
assert puts.tags[0].name == "example"
assert 200 in put.responses.keys()
assert put.responses[200].description == "Custom response"
