  D3D11: Use TextureHelper11 everywhere.
  
  This consolidates all texture allocation into ResourceManager11.
  It removes a lot of error checking and resource management code.
  In a few places we're storing some redundant information, like in
  TextureStorage11, we might store the Format pointer in two places,
  or the Texture's size.
