Automatic update from web-platform-tests WPT: consolidate top layer helpers Both close watcher and popover tests had a test_driver.bless variant that works with top layer. This consolidates them into /common/top-layer.js, which both sets of tests can use. Additionally, move isTopLayer from popover-utils.js to the new shared file. Then, the fullscreen tests can depend on that file, instead of depending on the popover utils file.
