vulkaninfo: handle previous driver versions

vulkaninfo: handle previous driver versions

Previously vulkaninfo assumed it would be run on a device
with a matching version. Now the autogeneration detects the
vulkan version and only reports extensions and versions
supported by the device. It will also output the correct
name according to the version.

Much of the autogen script was modified. Vendor abbreviations were pulled
into the autogen, dumping enums now adds the width so it is aligned,
using the built in order of types to eliminate needing forward
definitions, and dead code removal.
