#### Description

When the parameter for ssh_interface is set to "session_manager" we obvouslly admit that the SSM session is used.
The temporary_iam_instance_profile_policy_document can be created to attache some other references such as s3 bucket or secret_manager....

In my mind it could be a great things if the packer temporary role have the SSM Managed Core Policy attached by default in the case of SSM use case.

Could be a great option if we can use some existing policy in the accont.

#### Use Case(s)

If ssh_interface is set to "session_manager" so temporary_iam_instance_profile_policy_document have a temporary role with AmazonSSMManagedInstanceCore Policy attached.

#### Potential configuration

```
temporary_iam_instance_profile_policy_document use a JSON policy
temporary_iam_instance_profile_policies could a List[string] parameter with policies arns to attache on temporary role.
```
