Support dependencies between modules

[ffais]

We are trying to use the depends_on property between modules but for some reason it doesn't seem to work.
In the example below the modules are executed in parallel despite the depends_on directive.

module "personalize" {
  count    = data.coder_workspace.me.start_count
  source   = "registry.coder.com/modules/personalize/coder"
  version  = "1.0.2"
  agent_id = coder_agent.jupyter.id
  path     = "/scripts/run.sh"
  log_path = "/tmp/personalize.log"
}

module "jupyterlab" {
  count    = data.coder_workspace.me.start_count
  source   = "registry.coder.com/modules/jupyterlab/coder"
  version  = "1.0.30"
  agent_id = coder_agent.jupyter.id
  port     = 8888
  depends_on = [
    module.personalize
  ]
}

This is because Terraform is an infrastructure tool; it respects the depends_on but only while creating the resources.

Unfortunately, the modules run coder_script inside the workspace after the infrastructure is complete.

We are tracking the module's execution ordering in #93

And the upstream issue to track coder_script execution ordering is coder/coder#10352
