Add a new doxygen_index.md file, and use the Doxygen setting
USE_MDFILE_AS_MAINPAGE to include it as the contents of the Main Page.
Fixes #3689.
What does this PR do?
Adds some descriptive content to the "Main Page" of the raw Doxygen output at https://gdal.org/doxygen/index.html so it's not just mysteriously blank.
I've copied the intro paragraph about GDAL from the main website verbatim, and added some words of my own about the Doxygen site and how to use it.
