[wasm_builder] Remove array.new_data handling in global sections As of 2025/05/14, `array.new_data` is not a constant instruction, so can't be used in a global initializer. Also, data count section needs to appear right before the code section. Without `array.new_data` we don't need to generate it before the global section. Remove the code related to handling `array.new_data` in global sections. When `array.new_data` becomes constant, we can generate the data count section in its new place always, without having to specially handle it when it's used in a global section.

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).
Dart is free and open source.
