Doxygen comments and documentation - Add CI to generate it

[jgsogo]

From #63 review, some of the /// comments were a bit of unexpected for reviewers. They are doxygen-style comments for documentation.

We need to decide if we want to document the source or not so we can enforce it in either direction in our reviews.

Hi @jgsogo, can you please link me to these comments? In general, we will support doxygen style comments (and have not yet migrated our documentation which we still build internally).

[jgsogo]

You can find some comments starting with /// in the codebase, like https://github.com/Qiskit/qss-compiler/blob/main/include/HAL/TargetRegistry.h#L48

To clarify, we do wish to support Doxygen comments and the generation of Doxygen documentation.
