Re: [webauthn] Cleanup when creating discoverable credentials with attestations (#1560)

Yes, what I was thinking was something similar to this:

1. best-effort cleanup of credentials the site does not understand
2. eliminating edge cases that create spurious credentials when possible.

A delete/cleanup hint mechanism could be added directly to CredMan, I believe the only WebAuthn specific part is that non-resident credentials will always silently ignore cleanup. But since everything is a hint and the result is silent, who knows? 😄

e.g. a slightly different color bikeshed

```javascript
navigator.credentials.cleanup({
    type: "public-key",
    action: "retain",
    matching: [
        {id: "credhandle1"},
        {id: "credhandle2"}
]})
```
