feat(cpp): add cpp module scaffolding and plugin registration

[Divyateja2709]

hi @n1ckl0sk0rtge

This PR introduces the initial Maven and plugin scaffolding required for upcoming C/C++ language support in the Sonar Cryptography Plugin.

Changes Included
Added a new cpp Maven module
Registered the cpp module in the root pom.xml
Added the cpp dependency to sonar-cryptography-plugin/pom.xml
Updated SonarQube plugin configuration to recognize:
.c
.cpp
.h
source files through requiredForLanguages
Purpose

This PR establishes the build and plugin wiring needed before implementing:

C/C++ parsing
ANTLR grammar integration
OpenSSL detection rules
C/C++ detection engine support

This work is part of the initial language support setup outlined in the LFX mentorship project improvements for extending the Sonar Cryptography Plugin with C/C++ support.

Hi @Divyateja2709,

Thank you for your PR and for the time and effort you put into contributing to CBOMkit—we truly appreciate your interest.

You may have noticed that we are already working on adding C/C++ support to sonar-cryptography in PR #377. This approach differs from yours, as it relies on Sonar’s native C/C++ support package rather than ANTLR, similar to how the existing Java module is implemented.

Work on PR #377 is already quite advanced, and at this stage we are leaning toward this approach because we expect it to provide stronger support for cross-file symbol tracing through the Sonar infrastructure.

That said, we will keep your PR open for now until a final decision is made.
