[vm] Refactoring to existing safepoint mechanism
This CL makes some refactorings to the current safepoint mechanism:
* When owning safepoint level L we set current thread to be only at
safepoint level L (not Thread::Current()->current_safepoint_level()).
This ensures that after [WaitUntilThreadsReachedSafepointLevel] all
other threads are actually parked.
* When having nested safepoint scopes we increase operation count on
the level we own and all nested levels. This will (in later CL) allow
detection which closest scope we're in.

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).
Dart is free and open source.
