CPP: Support basic types + Add Dir Parameter

[joshualicht]

This PR contains:

• Support Basic Datatypes for CPP KvsValue (relating to Rust PR: Support basic types #46)
• Remove process_name and replace with a DIR argument (to align with Rust)

• Add InvalidArgument Errorcode (usecase example: directory is not a path)

• Move Tests-Directory to src/cpp/tests/ (to align with Rust)

(Also add Copyright Header for workflows in bm_kvs.cpp)

---

To Do before merging:

• Align on a common format being used for the json file. Refer this comment. Its currently implemented like in PR Support basic types #46, but IMHO it should be changed to the one presented in the comment.

--> ✅ Aligned with @vinodreddy-g (28.07.2025): Format from this comment will be used.

---

All Unittests were updated to the changes from this PR to stay with 100% Branches, 100% Functions and 100% Lines
(only the brackets in the kvsvalue_to_any switch case stay falsely reported as not hit)
Also the Any Stub is no longer needed for reaching the error case in any_to_kvsvalue, all stubs are removed and the dependency to the mock json parser/writer is used
