Create 'cpptools' VS Code / Theia plugin

[vince-fugnitto]

Description

The idea is to create a plugin for various cpptools (C/C++ Tooling) functionalities including but not limited to:

• additional syntax highlighting (ex: clang format, clang tidy, makefiles, ...)
• additional code intellisense (ex: clang format, clang tidy, makefiles, ...)
• additional commands (ex: generation of makefiles)
• additional custom tasks
• additional C/C++ snippets
• auto-completion for #include statements
