  D3D11: Consolidate Shader allocation.
  
  Similar to the InputLayout init, this adds a small helper type to act
  as a wrapper around shader init data (binary and size).
  
  This also adds error trapping to the blit shader compilation. It also
  removes the LazyResource2 class, and the CompileXS helper methods.
