Currently we have things called XPtr which are not what you get from ptr().
Old world:
handle->raw() returns RawObject* (tagged)
raw_obj->ptr() returns RawObject* (untagged)
After 6fe15f6df9:
handle->raw() returns ObjectPtr
obj_ptr->ptr() returns ObjectLayout*
New world:
handle->ptr() returns ObjectPtr
obj_ptr->untag() returns UntaggedObject*

As part of making the compiler and other subsystems independent
of `Isolate` we have to move various state from `Isolate` to
`IsolateGroup`.
The class_table and object_store were already moved to `IsolateGroup`.
This CL only replaces usages of `Isolate::{object_store,class_table}`
with the equivalent in `IsolateGroup`.

Also base these and the corresponding methods in _OneByteString on
functions in dart:_internal, so they can be used in other patches.

When using C++ value types to represent tagged pointers, we cannot use forward declarations for tagged pointers. This helps to break include cycles when attempting to keep IsXYZ predicates as tagged pointer member functions.
class_id.h also seems like a more natural place for these predicates, which were written before there was a class_id.h.

This removes the 3 fields from the classes in Dart and instead describes
the layout in C++ via a RawTypedDataView class (as already do with
normal RawTypedData). The existing "semi" TypedDataView handle class is
changed to be a real handle class.
This decreases performance of some microbenchmarks due to field guards
not being used anymore (before the JIT could add a field guard to view classes
guarding that only normal typed data is used as backing store (and not e.g. external
typed data)

Includes the following changes:
- Disable type checking in the service isolate when strong mode is
turned on. We don't yet have strong mode clean vmservice Kernel
binary available (Issue #31203);
- Introduce new Dart VM API to allow creating List<T> (T in {String, int}).
Current API only allows to create List<dynamic> and in strong mode
List<dynamic> is not assignable to List<T>. For now we limit this API to
a fixed number of core types for performance considerations (type
arguments can be canonicalized and cache ahead of time). We will
extend the API allowing creation of arbitrary List<T> if we will
discover the need for it later;
- Use this new API to fix CreateRuntimeOptions to create List<String>
and not List<dynamic>;
- Likewise fix OneByteString_splitWithCharCode to return List<String>
and not List<dynamic>;
Additionally this CL refactors how getters and setters are created
in object_store.h removing 500 lines of largely boilerplate code.

_StringBase is used everywhere as if it was assignable to String,
however it itself does not implement String, its subclasses do.
This change addresses this.
Also removes unused native runtime method from one of subclasses.

Refactor all remaning cases where the current zone is used through new(Isolate*) and remove this interface.
Removing this interface is needed to move towards multiple threads per isolate, and also makes the caller more aware of the scope of the zone used, reducing the risk of use-after-free.
Make the current thread and the stack zone created around native/runtime entries directly available in their body, saving an indirection (and optimized away if unused).

First steps towards general pretenuring support.
* Generalize Heap::Top/EndAddress.
* Add testing flag to exercise new code paths.
* Also update the slow-case runtime calls, to ensure a fresh block will be allocated in old.
Next steps are general invalidation of the generated code and adding a policy that doesn't blow up the store buffers), and freelist allocation.
