[Fix] Add origins option to requestFileHandle

[tomayac]

This makes the resources available globally. Initially this wasn't implemented in the extension, but the origins check is implemented now, so we need to update the code to make use of it. (Internally, the extension as a one-off upgrades all resources that were stored already as origins: '*'.)

Code Review

This pull request updates the requestFileHandle call in web/src/artifact_cache.ts to include an origins option. However, the CrossOriginStorageRequestFileHandleOptions interface needs to be updated to include this new property to avoid a TypeScript compilation error.

Important
