feat: Add support for all the assume-role attributes in the S3 remote state block

[asvinours]

Describe the solution you'd like

Add support for extra assume-role attributes for S3 remote_state backend.

Right now it looks like terragrunt supports role_arn, external_id and session_name but not the session duration, the session policy nor the session tags attributes.

terraform s3 backend documentation: https://developer.hashicorp.com/terraform/language/settings/backends/s3#assume-role-configuration

Describe alternatives you've considered

One alternative is to not use the terragrunt remote_state block and use a generate block and generate a terraform file for the backend configuration. Although doing this takes away the automatic deployment of the S3 bucket and dynamoDB table.

Additionally, assume_role_with_web_identity is not supported either. I am currently working around this by generating a ~/.aws/config file.
