netstack: Refactor tcpip.Endpoint.Read
Read now takes a destination io.Writer, count, options. Keeping the method name Read, in contrast to the Write method. This enables: * direct transfer of views under VV * zero copy It also eliminates the need for sentry to keep a slice of view because userspace had requested a read that is smaller than the view returned, removing the complexity there. Read/Peek/ReadPacket are now consolidated together and some duplicate code is removed. PiperOrigin-RevId: 350636322
