[CFE] Fix outline_suite time-regression on using generateKernelInternal in expectation tests

After 9a9b33eb0b950dec7524274e1eb06beb2e7ff020 running the outline suite
got noticeably slower.
For whatever reason it wasn't noticed until now though.

```
$ out/ReleaseX64/dart pkg/front_end/test/fasta/outline_suite.dart --traceStepTiming
[...]
[ 05:02 | 100.0% | + 2914 | -    0 ]: outline/wildcard_variables/unnamed_optional_parameter_no_default


             check errors: 0:00:00.301055 ms
      ErrorCommentChecker: 0:00:00.455464 ms
stress constant evaluator: 0:00:00.810962 ms
              write .dill: 0:00:01.040020 ms
                    print: 0:00:01.048330 ms
                   verify: 0:00:06.864096 ms
       match expectations: 0:00:07.527595 ms
                typeCheck: 0:00:12.512297 ms
                  outline: 0:04:31.713300 ms
```

The reason is that the outline also serializes the entire component (including the platform).
This CL disables that and instead gets (back) to:

With this CL:
```
$ out/ReleaseX64/dart pkg/front_end/test/fasta/outline_suite.dart --traceStepTiming

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).
