cherry-pick(#5997): Make tree items more actionable and add AppAction…

… for expanding the object tree * style: add `visibility` to tree expand triangles - The purpose of this is so that Playwright can perform actionability checks on the tree items. This will make operations involving expanding tree items much easier to perform in e2e. * feat(e2e): Add AppAction to expand the entire tree * fix: wait for loading indicator * test: add test for `expandEntireTree` * test: update `expandEntireTree` and tree selectors - Use dynamic aria-label for different tree implementations - Get rid of CSS ids which are only for testing - Update percy tree scope selector * chore(lint): remove unused variable * refactor(e2e): update tree locators Co-authored-by: John Hill <john.c.hill@nasa.gov>
