Re: [webauthn] Drop generic client extension processing? (#1730)

The downside is described in the top post:

> Unfortunately, [`fromJSON`] seems to be [incompatible with the generic extension pass-through provision](https://github.com/w3c/webauthn/pull/1703#discussion_r845941977), since for unknown extensions there's no way for the client to know which extension input values need to be converted to `BufferSource` values, and JSON has no standardized way to flag binary values.
