Bug 1930745 [wpt PR 49126] - Add Shared Storage trusted origins route…

… to RoutesBuilder (attempt 2), a=testonly

Automatic update from web-platform-tests
Add Shared Storage trusted origins route to RoutesBuilder (#49126)

We add a route for /.well-known/shared-storage/trusted-origins to RoutesBuilder in order to test custom data origins for shared storage.

See the explainer update: WICG/shared-storage#198.

(This is a second attempt, after closing the failed web-platform-tests/wpt#49112.)
