Store RequestInfo in Context instead of RequestInfoResolver dependency injection

**Depends on https://github.com/kubernetes/kubernetes/pull/33478**

The `RequestInfoResolver` is used in the proxy handler and in the authorization code. It is passed through half of the apiserver code base to be available at those locations. This PR uses the context instead, which is our natural dependency injection mechanism in the handlers.

`RequestInfo` and all tooling around is moved to `pkg/apiserver/request` temporarily to avoid dependency cycles. This is necessary as long as `pkg/apiserver` implements the proxy and other handlers. Those might move to `pkg/apiserver/handlers` probably later.
