[vm] Fix to ensure positions from CSMs in precompiled are as expected. Token positions in the CodeSourceMap are converted to line numbers (or kNoSourcePos if no line number) in precompiled mode. Fix the reader so that it uses kNoSource as the initial position in precompiled mode instead of kDartPrologue. This conversion never happens to token positions in PcDescriptors objects, so we should never treat a position coming from them (i.e., via GetTokenIndexForPC) as a line. Bug: https://github.com/dart-lang/sdk/issues/44492 TEST=Run on debug precomp trybot to verify fixed.

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.
