Migrate webauthn to the credentialmanager module.

This change moves the idl and implementation from
modules/webauth/ to modules/credentialmanager and implements
the creation of a publicKeyCredential via
navigator.credentials.create(). The call uses
WebAuthenticationClient to dispatch publicKeyCredential
operations to the browser-side mojo implementation.

This change also mocks the the browser-side implementation
of authenticator.mojom and adds layout tests using test_runner.

This change freezes the spec at WD05 for interop.
Spec WD05: https://www.w3.org/TR/2017/WD-webauthn-20170505/
