common : enable --offline mode without CURL support

This change refactors the download logic to properly support offline mode even when the project is built without CURL.

Without this commit, using --offline would give the following error:

error: built without CURL, cannot download model from the internet

even if all the files are already cached.

Small note here: at some point there was an idea to limit the usage of the json library as it is quite heavy on the build times. And specifically it seemed possible to make arg.cpp not depend on it. That's why here we used regexes. There are a few more json usages in this source file though, and with recent Docker changes, we introduced even more usages, so I guess this is not very realistic to happen.

Noting this in case there is interest to figure out a lighter approach that does not involve parsing json files when downloading files.
