This CL implements `NativeFinalizer` in the GC. `FinalizerEntry`s are extended to track `external_size` and in which `Heap::Space` the finalizable value is. On attaching a native finalizer, the external size is added to the relevant heap. When the finalizable value is promoted from new to old space, the external size is promoted as well. And when a native finalizer is run or is detached, the external size is removed from the relevant heap again. In contrast to Dart `Finalizer`s, `NativeFinalizer`s are run on isolate shutdown. When the `NativeFinalizer`s themselves are collected, the finalizers are not run. Users should stick the native finalizer in a global variable to ensure finalization. We will revisit this design when we add send and exit support, because there is a design space to explore what to do in that case. This current solution promises the least to users. In this implementation native finalizers have a Dart entry to clean up the entries from the `all_entries` field of the finalizer. We should consider using another data structure that avoids the need for this Dart entry. See the TODO left in the code.
