…new secrets support in container properties

Reference: #12997
Reference: #15469
Reference: https://aws.amazon.com/about-aws/whats-new/2020/10/aws-batch-now-supports-custom-logging-configurations-swap-space-and-shared-memory/

Changes:

```
* data-source/aws_batch_compute_environment: Add `tags` attribute
* data-source/aws_batch_job_queue: Add `tags` attribute
* resource/aws_batch_compute_environment: Add `tags` argument
* resource/aws_batch_job_definition: Add `tags` argument
* resource/aws_batch_job_queue: Add `tags` argument

BUG FIXES

* resource/aws_batch_job_definition: Prevent unexpected plan difference for `container_properties` argument value with new secrets support
```

With the recent Batch service updates, the new secrets support in container properties would show as a confusing plan difference:

```
              ~ container_properties = jsonencode(
                  ~ {
                        command              = [
                            "echo",
                            "test",
                        ]
                      - environment          = [] -> null
                        image                = "busybox"
                        memory               = 128
                      - mountPoints          = [] -> null
                      - resourceRequirements = [] -> null
                      - secrets              = [] -> null
                      - ulimits              = [] -> null
                        vcpus                = 1
                      - volumes              = [] -> null
                    }
                )
```

This augments the Batch equivalency to ensure the canonicalized API response of an empty secrets array matches no secrets configuration.

While verifying the updates, this fixes the following two AWS GovCloud (US) test failures due to hardcoded partition handling:
