DPF(C++): First try for a Markdown DPF C++ API doc 2027R1

No description provided.

• There must be only one main final toc.yml
• Change Markdown file names to have: no numbers, no underscore (use dashes), and no capital letters

[PProfizi]

The process is correct if:

• Doxygen only treats the API reference, leave the original Markdown doc source alone
• Make sure Doxygen is the right version
• Seaborg translates only the Doxygen output
• Ansys Doxygen config should still be the one from the repo api_documentation (branch to confirm)
• Try and use Seaborg config to filter-out protected and private members (which Doxygen does not do for XML despite its config saying not to). Beware the Seaborg config may not work either.

Try seaborg-config.json:

{
    "excludeProtectionLevels":  [
                                    "private",
                                    "protected"
                                ]
}
