  Vulkan:Add Swiftshader configs
  
  Add Swiftshader configs to existing test instantiation macros for all ESX
  variants. This causes Swiftshader to be used to run end2end tests.
  
  Added detection code to know when tests are running on Swiftshader and skipping
  a number of fails initially.
  
  Note that when running ANGLE end2end tests within Chromium build on Win32 bots
  there were crashes with Swiftshader config for tests that should have been skipped.
  Due to this, just skipping Swiftshader configs on Win32 for now.
