Automatic update from web-platform-tests
Refine crossOriginIsolated implementation for workers (#25748)

- Fix WindowOrWorketGlobalScope.crossOriginIsolated behavior for
   workers.
   - For SharedWorkers and ServiceWorkers it always return false. See
     https://crbug.com/1131403 and https://crbug.com/1131404.
 - Rename ExecutionContext::IsCrossOriginIsolated to
   CrossOriginCapability. This is aligned with
   https://html.spec.whatwg.org/C/#concept-settings-object-cross-origin-isolated-capability.
 - Fix wpt/html/infrastructure/safe-passing-of-structured-data/shared-array-buffers/blob-data.https.html.
   I originally planned to do that in
   web-platform-tests/wpt#24600 but I couldn't
   do that due to some flakiness.
 - Add more tests for workers in
   wpt/html/cross-origin-embedder-policy/cross-origin-isolated-permission.https.html.
