Clean up WebAuth browsertests.

Do some general clean-up and increase robustness:
 -- Reorder some methods/constant declarations,
 -- Add two new tests that use FakeFidoDiscoveries to ensure that
    when there are supposedly simultanenous requests, the first one
    is well underway when the second one starts,
 -- Use ScopedFakeFidoDiscoveryFactory for all tests,
 -- Make tests use TestCallbackReceiver.

Manage the lifetime of the browser-side AuthenticatorImpl properly.

The content::AuthenticatorImpl implementation of the corresponding Mojo
interface is now reset (all pending requests dropped) every time the
owning frame navigates cross-document.

The corresonding browser tests have been updated and cleaned up.
