r/aws_globalaccelerator_endpoint_group: add attachment_arn to endpoint_configuration

[tcarreira]

(continuing #37269)

Description

In #35991 we added support for making cross account attachments (docs). There was one part missing, using them in the endpoint group for the Global Accelerator (AGA).

This add support for setting this field AttachmentArn: https://docs.aws.amazon.com/global-accelerator/latest/api/API_EndpointConfiguration.html

Relations

Output from Acceptance Testing

new test:

❯ make testacc TESTS=TestAccGlobalAcceleratorEndpointGroup_crossAccountAttachment PKG=globalaccelerator
make: Verifying source code with gofmt...
==> Checking that code complies with gofmt requirements...
TF_ACC=1 go1.22.7 test ./internal/service/globalaccelerator/... -v -count 1 -parallel 10 -run='TestAccGlobalAcceleratorEndpointGroup_crossAccountAttachment'  -timeout 360m
=== RUN   TestAccGlobalAcceleratorEndpointGroup_crossAccountAttachment
=== PAUSE TestAccGlobalAcceleratorEndpointGroup_crossAccountAttachment
=== CONT  TestAccGlobalAcceleratorEndpointGroup_crossAccountAttachment
--- PASS: TestAccGlobalAcceleratorEndpointGroup_crossAccountAttachment (410.65s)
PASS

note: I had to run this test without the PreCheck acctest.PreCheckOrganizationsAccount(ctx, t) bc I don't have multiple AWS accounts on different Orgs. I should not affect the result.
