[VPP-2129] VPP plugin Compatibility with C++

[mohammadmahdi255]

Hello,

I would like to know if it is possible to create a VPP plugin using C++. I have attempted to make it compatible, but I encountered several issues related to C++ policies:

Use of reserved keywords: variable names such as class, template, and new.
Converting void* to another type without casting.
Comparing unsigned and signed integers.
Overflow warnings.
Performing arithmetic calculations with void*.

I can fix these issues, but I wanted to check if they are acceptable to address.

Thank you!
