[web] Use TrustedTypes from pkg web. (flutter#6273)

During the `package:web` migration, some packages that needed the TrustedTypes API defined those as custom JS-interop.

In `google_identity_services_web`, the names of the JS-interop types clashed with those from the incoming package:web, breaking the build.

In `google_maps_flutter_web`, the whole definition code is redundant now that the standard API is exposed through package:web.

Part of: flutter/flutter#117022
