Seungha Yang c3cf9521a5 d3d11: Update library doc 
* Private header name is changed to gstd3d11-private.h to follow
  naming convention
* Add Since mark everywhere
* Update member variable names to be consistent with the other
  object implementations in this library
* Correct outdated documentation
