This patch also: - introduces CollectElementsWhileHasResult(Typed) to collects elements in and array. - uses more QM_TRYs in our code. - changes some pieces of code to match our coding gulideline. Also, using CollectElementsWhileHasResult and CollectWhileHasResult helps the code in cache/DBSchema to ensure the funtion returns an error result when ExecuteStep returns an error in the loop's condition check consistently. Before this change, DOM cache code often doesn't check the result from ExecuteStep after exiting the loop. Differential Revision: https://phabricator.services.mozilla.com/D97466
