[vm/concurrency] Change "RunWithStoppedMutators" to use "deopt safepoint operation scope"

The "RunWithMutatorsStopped" wrapper is used in places where the invoked
callback can cause deoptimization of code. It should therefore ensure
it's running with a "deopt safpoint operation scope" to ensure mutators
are stopped at well-defined places that allow lazy-deopt.

Issue https://github.com/dart-lang/sdk/issues/45213

TEST=Existing code base, will add "fuzzer"-like test to nightly/weekend builders.

Dart

A client-optimized language for fast apps on any platform

Dart is:

  • Optimized for UI: Develop with a programming language specialized around the needs of user interface creation.

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app.

  • Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.

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).
