Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=47109
Signed-off-by: Brendan Shanks <bshanks at codeweavers.com>

v6: As recommended by Alexandre, the JSON file is now generated by
make_vulkan and stored in resources.
The library_path in the JSON file is now a relative path, this is
simpler and is what NVIDIA and AMD ICDs do on Windows.
