Merge #14832: docs: Add more Doxygen information to Developer Notes

a62e667296 docs: Add more Doxygen information to Developer Notes (Jon Layton)

Pull request description:

  Update information about Doxygen in `doc/developer-notes.md`.

  Alternatively, this could have its own file (like `doc/web-documentation.md`), since there are installation steps included.

  For example, I had to run:
  ```
  brew install doxygen graphviz
  ```
  on MacOS, otherwise failures occurred.

  This information could also be linked to the `doc/release-process.md`.

Doxygen comments
-----------------
Coding Style (Python)
---------------------
To facilitate the generation of documentation, use doxygen-compatible comment blocks for functions, methods and fields.
Refer to [/test/functional/README.md#style-guidelines](/test/functional/README.md#style-guidelines).

Bitcoin Core uses [Doxygen](http://www.doxygen.nl/) to generate its official documentation.

Coding Style (Python)
---------------------
Refer to [/test/functional/README.md#style-guidelines](/test/functional/README.md#style-guidelines).
Before running `make docs`, you will need to install dependencies `doxygen` and `dot`. For example, on MacOS via Homebrew:
```
brew install doxygen --with-graphviz
```
