fe4837afcc handle_wrap: IsRefed() -> HasRef()
Rename slightly to HasRef() at bnoordhuis’ request.
Better reflects what we actually do for this check.

96a9439fd2 Revert "handle_wrap: IsRefed -> Unrefed, no isAlive check"
This reverts commit 9bb5a5e2a1.

This API is not suitable because it depended on being able to
potentially access the handle's flag after the handle was already
cleaned up. Since this is not actually possible (obviously, oops)
this newer API no longer makes much sense, and the older API is more
suitable.

API comparison:
IsRefed -> Has a strong reference AND is alive. (Deterministic)
Unrefed -> Has a weak reference OR is dead. (Less deterministic)

a58d4839af src: simplify handlewrap state tracking logic
This also updates the tests to expect that a closed handle has no
reference count.

9bb5a5e2a1 handle_wrap: IsRefed -> Unrefed, no isAlive check
This fixes my perceived usability issues with 7d8882b. Which, at the
time of writing, has not landed in any release except v6 RCs. This
should not be considered a breaking change due to that.

It is useful if you have a handle, even if it has been closed, to be
able to inspect whether that handle was unrefed or not. As such, this
renames the method accordingly. If people need to check a handle's
aliveness, that is a separate API we should consider exposing.

7d8882ba9a handle_wrap: expose an isRefed() check to JS
This allows third-party tools to check whether or not a handle that
can be unreferenced is unreferenced at a particular time.
Notably, this should be helpful for inspection via AsyncWrap.

Also, this is useful even to node's internals, particularly timers.
