async_hooks: remove promise object from resource
While it doesn't make any difference now. In the future PromiseHooks
could be refactored to provide an asyncId instead of the promise object.
That would make escape analysis on promises possible.

Escape analysis on promises could lead to a more efficient destroy hook,
if provide by PromiseHooks as well. But at the very least would allow
the destroy hook to be emitted earlier. The destroy hook not being
emitted on promises frequent enough is a known and reported issue.
See https://github.com/nodejs/node/issues/14446 and
https://github.com/Jeff-Lewis/cls-hooked/issues/11.

While all this is speculation for now, it all depends on the promise
object not being a part of the PromiseWrap resource object.

test: make crashOnUnhandleRejection opt-out
This commit removes `common.crashOnUnhandledRejection()` and adds
`common.disableCrashOnUnhandledRejection()`.

To reduce the risk of mistakes and make writing tests that involve
promises simpler, always install the unhandledRejection hook in tests
and provide a way to disable it for the rare cases where it's needed.

async_wrap: use kTotals to enable PromiseHook
Keep a total of enabled hook callbacks in kTotals. This value is used to
track whether node::PromiseHook (src/async-wrap.cc) should be enabled or
disabled.

Don't enable node::PromiseHook, using enablePromiseHook(), until a hook
has been added. Then, using disablePromiseHook(), disable
node::PromiseHook when all hooks have been disabled.

Need to use a native test in order to check the internal field of the
Promise and check for a PromiseWrap.
