[vm/concurrency] Make the IGs own the initial static field value table As part of making lightweight isolates work in JIT, we will need to ensure that whenever a new isolate is spawned it will get it's initial global field table populated. In order to achieve this we make the isolate groups initial field table the authoritive place where we a) register initial static field values b) serializer reads them from, deserializer writes them to This allows us to also remove the `FieldLayout::initial_saved_value_` that was present for both static and non-static fields. In reality this initial saved value is only meaningful for static fields though it was kept in memory as well as (de)serialized even for non-static fields. The one place where it was actually used for non-static fields was incorrect and should instead use `null`. The removal of this field results in net removal of code in this CL.

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.
