package/vulkan-sdk: new package

The principle component of this is the new volk meta-loader which is
required for more recent versions of vulkan-tools. There does seem to
be a little confusion with github Releases lagging behind tagged
versions of the sdk. I've gone for the latest SDK version to stay as
closely aligned to the rest of the system as I can.
