Add support for empty state to <select>, <select1> and <rank>

**Description**

The ``, `` and `` question types can use the [choice-filter](https://docs.getodk.org/form-logic/#filtering-options-in-select-questions) to limit options (itemset) based on the answer to a previous question. In some cases, all options may be filtered out, leaving these question types empty, i.e., not displaying any option in the UI.

**To do:**
- [ ] Research and determine priority
- [ ] Design a consistent user interface and experience for this empty state.
- [ ] Implement the empty state in ``, `` and ``.
- [ ] Automate tests to verify the UIUX

Start by reviewing how choice-filter results are rendered for , , and , then read the linked filtering-options documentation for expected behavior. Define a consistent empty-state experience and its priority before implementation. Done means all three question types display the agreed state when filtering removes every option, with automated UI tests covering it.
