fix(sql lab): Save Dataset Modal Autocomplete should display list when overwritting (#20512)

* Save Dataset Modal:

- Use our Select component as substitute of the Autocomplete one so options are loaded initially without the user having to trigger a search and we are mosre consistent with the rest of the app
- Changing datasetId to lowercase so when custom props get into the DOM we don't get warning related to invalid formatting
- We extracted the dropdown out of the radio because it causes invalid click handling when an option is selected
- Updated tests

* Save Dataset Modal:

- Update missing test for DatasourceControl

* Save Dataset Modal:

- Remove conditional from load options function since only guest users dont have userId, and if that is the case they wont reach this part of the application

* Save Dataset Modal:

- Remove unused comment

* Save Dataset Modal:

- Add getPopupContainer as prop for Select component

* Save Dataset Modal:

- Add tests for our new getPopupContainer prop in Select component. So if passed it gets called.

* Save Dataset Modal:

- use lowercased property when calling post form data

* Save Dataset Modal:

- Update tests so there is no need to define a null returning func

* Save Dataset Modal:

- Including getPopupContainer from PickedSelectProps instead
- Updating definition in SelectFilterPlugin
