v.io/coreveyron/runtimes/google/ipc/stream: use verror2 instead of verror1

This change eliminated the use of verror1 in
        v.io/core/veyron/runtimes/google/ipc/stream/manager/manager.go
        v.io/core/veyron/runtimes/google/ipc/stream/proxy/proxy.go

It also eliminated unused identifiers from the exported verror1 interface.

Tested with
        cd release/go/src/v.io
        v23 go test ./...
        v23 test run vanadium-go-test
