Pull request description:
_This is a piece of #21878, chopped off to ease review._
* convert standalone `IsSelectableSocket()` to `Sock::IsSelectable()`
* convert standalone `SetSocketNonBlocking()` to `Sock::SetNonBlocking()`
This further encapsulates syscalls inside the `Sock` class and makes the callers mockable.
