Bug 1706884 [wpt PR 28637] - Make web test for SAB in IndexedDB a WPT, a=testonly

Automatic update from web-platform-tests Make web test for SAB in IndexedDB a WPT The web_test checking that a SharedArrayBuffer cannot be serialized into IndexedDB was failing because it was served inside a non-cross-origin-isolated page, which could not create a SharedArrayBuffer. This CL turns that into a Web Platform Test and adds the appropriate COOP and COEP header which make the page cross-origin-isolated, enabling instantiation of SharedArrayBuffer.
