option to enforce block generation

Fixes issue with auto-generated ARON impl for default d'tor, e.g.,

   ~Foo() = default {};

after last hotfix.

@peller you recent changes broke the generation of ARON files in armarx::navigation. The issue was that softReset() was empty and the curly brackets weren't generated.

Here, I explicitly added this enforceBlockGeneration member that can be set in the ARON code generation. See dependent PR in RobotAPI
