  Add generated tables to mirror D3D11 format support.
  
  *re-land with fix for test build*
  
  These tables can save us on startup time. Instead of querying the
  tables, we can keep certain assumptions about texture formats
  because certain formats are guaranteed to be supported in various
  feature levels.
  
  Testing with angle_perftests indicates this patch series will save
  about 50% of the time we spend in Renderer11::initializeDevice.
