Serializing the object stored in a handle may require allocation, so serialization of the current (weak) persistent handles should not be done under a no safepoint scope. Instead, retrieve the stored objects and any needed metadata for the current (weak) persistent handles under a no safepoint scope, and then separately serialize the retrieved information outside of that scope. Fixes https://github.com/dart-lang/sdk/issues/62978. TEST=vm/cc/Service_PersistentHandles on vm-dyn-*, which revealed this issue.

Dart
An approachable, portable, and productive language for high-quality apps on any platform
Dart is:
-
Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns.
-
Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web.
-
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app. Diagnose app issues using DevTools.
Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:
-
Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.
-
Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
