Remove collection infrastructure blocks from `main`

[Alexander Streed]

Dependent on #13363

Remove the following modules on the main branch:

• prefect_aws.ecs
• prefect_gcp.cloud_run
• prefect_gcp.aiplatform
• prefect_azure.container_instance (This one is missing a deprecation warning on the class itself. We should add it to the 2.x branch)
