  Avoid a copy in TextureStorage11::setData
  
  This is essentially a reland of 9cf9bcbecaa1e54a47a92eb784e7f591f7b65c57
  
  This code always allocates a new memory buffer for the texture memory,
  picks a load function to copy/convert the input data into it, and the
  uploads.
  
  In the case where the input format matches the upload format we should
  be able to skip the allocation and copy and be much happier.
