Seungha Yang a040450685 d3d11compositor: Performance optimization
Removing glvideomixer-like nuance (it was initially referenced)
and rewriting element since it's not an optimal design at all
from performance point of view.

* Remove wrapper bin (and internal conversion/upload/download elements)
  which will waste CPU/GPU resources. Conversion/blending can be done by the
  d3d11compositor element at once.
* Add support YUV blending without RGB conversion.
  The RGB <-> YUV conversion is completely unnecessary since YUV textures
  support blending as well.
* Remove complicated blending operation properties since it's hard
  to use from application point of view. Instead, adding "operator" property
  like what compositor element does.
