Add parameterized resource identity to aws_route_table

[jar-b]

Description

Adds resource identity support to the aws_route_table resource. This is a parameterized resource with a single attribute, id, corresponding to the route table ID generated by AWS during creation.

The identity based import section in the registry documentation is adapted from the template used in the tfplugindocs tooling. See hashicorp/terraform-plugin-docs#496.
