  Vulkan: Load layers relative to executable dir.
  
  Instead of baking in a relative path and expecting the app to run from
  a fixed directory, we can change the CWD at runtime so the layers can
  load relative to the current executable directory.
  
  Future alternatives could include modifying the layers SDK to provide
  a path dynamically, but for now the relative paths must be baked in
  at compile-time.
