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.
