Use setup_test_component_platform helper for select entity component tests instead of hass.components (#114412)

* Use `setup_test_component_platform` helper for select entity component tests instead of `hass.components`

* Use _values instead of _attr_current_option

* Clean up

* Set default current_option for second mock entity
