Slava Egorov a17d709a1d Revert "[tools] Allow precompiling gen_kernel and compile_platform" 
This reverts commit 5cda2a871c.

Reason for revert: broke Flutter build. 

Original change's description:
> [tools] Allow precompiling gen_kernel and compile_platform
>
> When iterating on core library changes or changes in the AOT compiler
> many seconds are wasted waiting on gen_kernel/compile_platform to
> parse Dart code. This happens because we are running these tools
> from sources on prebuilt Dart SDK.
>
> This CL allows SDK developer to opt-in into AOT compiling these
> tools by adding `precompile_tools=true` to their DART_GN_ARGS.
>
> AOT compilation is performed using prebuilt SDK - so these
> executables do not need to be recompiled if core libraries or
> VM changes reducing iteration cycles.
>
> pkg/vm/tool/precompiler2 is tweaked to detect when DART_GN_ARGS
> contains `precompile_tools=true` and use precompiled
> gen_kernel.exe instead of running it from source.
>
> Using precompiled compile_platform takes vm_platform_strong.dill
> build from 20 seconds to 3 seconds.
>
> Using precompiled gen_kernel takes small benchmark build from
> ~10 seconds to 2 seconds.
>
> TEST=manually tested

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).
