controller-tool: Fix configuration format

[JayFoxRox]

The configuration format is pretty bad. 2 of the available files are also not correct anymore.

The idea behind the format is to make it possible to have one json file per product or protocol.
The same files (or files generated from it) are supposed to be fed into xbox emulators later.
Ideally they'll even be used to generate the xboxdevwiki pages [or replace them].
This also means we'll need tools to dumb all the USB configuration descriptors and put it in each config.
