[Feat] (Diligent): wire stencil and color-mask state into state PSO

Browse Source 
CreatePipelineFromState now applies GL_STENCIL_TEST state (front/back funcs,
ops, read/write masks) and GL color write mask. DrawFromState sets the stencil
reference before drawing. All Diligent local tests still pass.
