Re: [webauthn] Delete per RP ID Signature counters

Regarding 
`@akshayku notes that msft's platform authnr impls per-RPID counters`

I may have misspoken on the call. We implement per credential ID based counters and not RP based counters.

I agree with @agl and @rlin1 here. Per-RP based counters is a mistake and what we meant that it is per-credential based. 

So there are three options for the authenticator:
- Authenticator supports no signature counter.
- Authenticator support global signature coutner.
- Authenticator support per-credential signature coutner. 

I think we should recommend per-credential signature counter.
