fix: allow definition of multivalued user profile attributes

In order to replicate the existing userprofile configuration, we need to support the multivalued attribute.

We now support the `multi_valued = bool` attribute.

Example:
```hcl
  attribute {
    name = "myAttr"

    multi_valued = true

    validator {
      name = "options"
      config = {
        options = jsonencode(["opt1", "opt2", "opt3"])
      }
    }

    annotations = {
      foo = jsonencode({ "key" : "val" })
    }
  }
 ```

 Fixes #1064
