If more than one of the allowed targets is specified in an `aws_route`
resource, we should provide an error message that does not include
`route_table_id` as a valid target, since `route_table_id` is actually
a required argument.

IPv6 wasn't supported for adding routes to the internet gateway.
Resulted in a message as follows:
```
Error creating route: MissingParameter: The request must contain the parameter destinationCidrBlock or destinationIpv6CidrBlock
```

This commit changes the behaviour of the `ExistsFunc`, where by default
lack of a route table (e.g. already removed, etc.) would cause an error
to be thrown. This makes is hard to carry out any action e.g. plan,
refresh, or destroy, that rely on the route table existance check.
Also, make error messages a little better in terms of wording, etc.

The symptom is that a route "fails" to create, then every subsequent
`terraform apply` fails with RouteAlreadyExists.
CreateRoute was succeeding but the very next DescribeRouteTables
was not listing the new route.
The "find route in table" helper code was not properly handling routes
with no destination CIDR block - like vpc_endpoint routes - so if one of
those routes would come up before the target route in the loop, we'd get
a crash.
Fixes#6337
Fixing basic acceptance test.
Adding warning to website about mixed mode.
Adding exists to aws_route.
Adding acceptance test for changing destination_cidr_block.
