[strawman] Symbol.thenable proposal

It's worth noting that the driving use case here is coming from NodeJS
development hitting issues where the guaranteed result for dynamic import
resolution can't be assumed to be a module namespace, although please
correct me if I'm wrong here Gus.
Alternatively could this mitigation be handled by creating a
`Promise.resolveStrict` primitive that explicitly opts-out of thenable
resolution in the promise chain?
I'd think we are getting further and further away now from third-party
promise implementation interops, that such approaches might make sense to
consider at this point, in the name of returning to more well-defined
