Add syntax highlighting for @module doxygen comments

[rdong8]

Feature Request

Doxygen now supports @module to document a file that is a C++20 module. The @module part is not highlighted by the current syntax highlighting, unlike @file.

@rdong8 Doxygen comment tag highlighting is implemented by VS Code itself and not the C/C++ extension: https://github.com/microsoft/vscode/issues

Though we probably want to add it to the enum items for the "C_Cpp.doxygen.sectionTags" setting. Could you do that @sean-mcmanus?

@bobbrow Sure, created an issue to track that.
