Reland "[ DDS ] Fix DDS AOT snapshot build rules"

This is a reland of commit 0a393f1b697671a4bb42ba0ec9b1c4dda91b013b

The problem was that the checks for whether or not dartaotruntime
existed were always returning false on Windows because the ".exe" suffix
wasn't being taken into account. Patchset 2 addresses this.

Original change's description:
> [ DDS ] Fix DDS AOT snapshot build rules
>
> dds_aot.dart.snapshot was not being generated for runtime build targets,
> and dds.dart.snapshot was being built regardless of whether or not we
> were building for an IA32 target.
>
> This change also adds a check for IA32 in 'dart run' so the "Could not
> find dds_aot.dart.snapshot. Have you built the full Dart SDK?" message
> isn't printed when we fall back to using dds.dart.snapshot.
>
> This change also reverts 2cc08595a644cd6761730629af7ad86669655a2a, which
> failed to fix the issue it was attempting to fix.
>
> TEST=pkg/vm_service tests

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).
