src: cleanup per-isolate state on platform on isolate unregister
Clean up once all references to an `Isolate*` are gone from the
`NodePlatform`, rather than waiting for the `PerIsolatePlatformData`
struct to be deleted since there may be cyclic references between
that struct and the individual tasks.
