Subject: [PATCH] Disable Crossgen2 Json CG2 composite job

The CG2 composite profile for the Json crossgen2 scenario consistently hits ILCompiler.CodeGenerationFailedException (IndexOutOfRangeException in CorInfoImpl.HandleToModuleToken) during publish, and on Windows runs has caused crank to hang, blocking the rest of the jobs in benchmarks-ci-01 and benchmarks-ci-02. Disable it via its condition until the underlying crossgen2 issue is resolved.
