Daco Harkes 532c116cd2 [vm] Implement NativeFinalizer 
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.
