[cloud] ec2_vpc_route_table: ignore routes without DestinationCidrBlock - fixes #37003 (#37010)

Browse source 
* [cloud] ec2_vpc_route_table: ignore routes without DestinationCidrBlock

Add module warnings rather than silently skipping

* Permit warnings for routes tables containing vpc endpoints to be turned off

* Add tests to ensure a VPC endpoint associated with a route table does not result in a traceback
