Documentation: refactor "api-index.sh" for out-of-tree builds

Browse Source 
The "api-index.sh" script generates an index of API-related
documentation. The script does not handle out-of-tree builds and thus
cannot be used easily by Meson.

Refactor it to be independent of locations by both accepting a source
directory where the API docs live as well as a path to an output file.
