[gardening] Make more robust test for mutator bit stealing mechanism

We also disable the test in hotreload mode, because threads that are
stuck in ffi calls don't participate in hot-reload requests.

This is something we may want to look into. Right now it's conservative in
the sense that if an embedder did a `Dart_LookupClass()` in such a ffi call
and then a reload happened, such a handle would possibly hold pointer to
an old class object and weird things may happen.

This fixes test failures in hot reload / rollback mode of

  `vm/dart/isolates/many_isolates_blocked_at_ffi_test`

and also make it more robust.

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).
