Subject: vulkan: update to header 1.0.42

Updated all necessary files to 1.0.42.  This includes the various
headers as well as the loader, and the parameter validation, object
tracking, and threading layers.  Additionally, bump all layer JSON
files to 1.0.42.

Also, in this change:
  - Enable loader extension automation so that the loader now
    generates all extension entry-points automatically during build
    to reduce likelihood of missing a critical piece on header
    update.
  - Enable layer dispatch table extension automation for the same
    reason.
  - Fixes from Mark Lobodzinski and Tony Barbour to resolve crash
    in loader when working with Intel's Windows driver due to
    GetInstanceProcAddr getting called on inappropriate command
    names.
