Resolve "Deploy Doxygen documentation"

What does this MR do?

Deploys Doxygen documentation into Netlify server. The process is done manually.

• Docusaurus creates a build directory build where where it places the generated static files resulting from the documentation.
• We now also run Doxygen for each tag (only when running in master) and dump the html result into the build directory so that it matches docusaurus directory tree.

Is there something that needs to be double checked?

So far everything seems ok
