Fix responses for UpdateFabricLabel to match the spec. (project-chip#…

…15122) * Fix responses for UpdateFabricLabel to match the spec. 1. Send a NOCResponse instead of a status response, like the spec says. 2. Implement the "check for fabric label collision" bit from the spec. 3. Update the name of the "Fabrics" attribute to match the spec. 4. Add a test for UpdateFabricLabel and reading the Fabrics attribute both before and after updating the label. Fixes project-chip#15114 * Fix handling of chip_tests_variables_has inside #each. It looks like #each breaks the .parent chain that chip_tests_variables_has relies on. Just manually hook that up.
