This is a reland of commit cb9ecbc363
This reland only turns on the entry point verification flag by
default in AOT mode. After Flutter tests that use native access
in JIT mode have been appropriately updated, a followup CL will
turn this flag on by default in JIT mode as well.

Changes the default value of the --verify-entry-points flag
to true.
Changes the default value for the check_is_entrypoint argument to
to the Invoke/InvokeGetter/InvokeSetter flags to true. The mirrors
library implementation and calls via vm-service explicitly pass

Add annotations as needed, such as annotating classes with

All uses of `PortMap::Create()` would call `PortMap::SetPortState()`
after creating the port. To avoid acquiring the port map lock twice, we
can initialize the state already in `PortMap::Create()`.
Additionally we fix an existing issue by making the isolate's main port
a control port (instead of leaving it as a `kNewPort`).
As a side-effect we'll no longer have any allocated ports with state
`kNewPort`.
We also remove the unused `PortMap::IsLocalPort()`

Message is a C++ type with a simple ownership model appropriate for
std::unique_ptr. This CL applies the following changes:
1. All uses of "new Message(...)" are replaced with
"Message::New(...)", which is effectively
"std::make_unique<Message>(...)". (The latter was only added in C++14,
but Dart still compiles in C++11 mode.)
2. All owning Message* are replaced with std::unique_ptr<Message>. The
notable exception is MessageQueue, which still uses raw Message*
internally to simplify the linked list handling.
3. All "delete message;" statements are removed.
4. Uses of "NULL" replaced with "nullptr" as necessary.

For example setting return value unwraps handles and stores
raw pointer values to the stack which might race with GC
in another thread.
This CL adds assertions in helper methods from Api class which
unwrap API handles and fixes all places that were revealed by
those assertions.
Caveat: we still permit to check whether handle contains
Smi or not without entering VM state - because GC does not
change this property.

Both thread and isolate have sticky error fields. Dart API was using
isolate's sticky error, while Dart code was using thread's sticky error.
There was a one-way move of a thread's sticky error into isolate
when thread was unscheduled.
This causes a problem as error in the isolate may go unnoticed and
repeated unscheduling/re-scheduling might end up overwriting the error
in the isolate (which triggers the assertion).
To solve this problem, this CL:
* Cleans up Dart API which manipulates isolate's sticky error, so
isolate's sticky error is never set directly.
* When sceduling an isolate to a thread, sticky error is moved back from
isolate (if any).
With this changes, thread's sticky error is always used if thread is running,
and isolate's sticky error is only used to hold sticky error while
isolate has no thread.
