[cloud] Make ec2_vpc_nat_gateway results consistent (#24042)

Browse Source 
Ensure newly created NAT gateways get converted to snake dict
Remove custom code, and associated test, for generating snake
dict and use `camel_dict_to_snake_dict`
Make use of `required_if` rather than bespoke parameter checks
Remove ec2_vpc_nat_gateway from pep8 legacy files list
