internal/graphicsdriver/directx: bug fix: wrong offsets

Browse Source 
* Wrong offsets were speicified when creating a constant buffer view and
  a shader resource view.
* Wrong root descriptor tables were speicified. For one draw command,
  one descriptor table for a constant buffer and textures should be used.

Updates #2198
Closes #2201
