Bug 1896018 [wpt PR 46192] - [FedCM] Replace the scopes API with the fields API, a=testonly

Automatic update from web-platform-tests
[FedCM] Replace the scopes API with the fields API

This implements the new proposal here:
https://github.com/fedidcg/FedCM/issues/559

If one or two but not all of ["name", "email", "picture"] are requested,
we reject the promise. Otherwise, we show the disclosure text if
either field is not specified or contains the three default fields.
All specified fields are passed to the server in the "fields" parameter;
if fields was unspecified we pass the default fields here.

All this is for forwards compatibility.
