Allow the provider default_tags to be exposed as a data source so that the tags can be added to other areas where they are not automatically applied, like the volume_tags of a aws_instance or the tag_specifications of a aws_launch_template.

i'm not 100% on how we set empty values, but we could also always set the "tags" field if we do something like

tags := defaultTagsConfig.GetTags()

...

if len(tags) > 0 {
    tags = tags.IgnoreAws().IgnoreConfig(ignoreTagsConfig)
}

if err := d.Set("tags", tags.Map()); err != nil {		
    return fmt.Errorf("error setting tags: %w", err)
}

only trouble with that is semgrep doesn't like it - ignore must accompany d.Set("tags"...)
