enable `--inline-suppr` by default

[firewave]

Currently we do not enable the handling of inline suppressions by default. We should enable this since it just makes sense and also to avoid unexpected warnings from already annotated code.

There's a caveat though if the code is being processed by multiple Cppcheck versions and the finding is no longer reported. This might lead to unexpected unmatchedSuppression warnings (which was proposed in #77).

Because of this it should only be implemented after unmatchedSuppression is no longer part of --enable=information which will hopefully be the default behavior starting with Cppcheck 2.18.
