D3D12: Handle special shader effect cases

Like when there is only one shader is given by the ShaderEffect item, or
when texture providers disappear (use a dummy texture in this case).
Changing the cull mode works now too. Fix also the inconsistent naming
(activate -> use) for textures in the glpyh cache. The cbuffer is now
correctly aligned. Filtering and wrap modes are now taken from the
texture, meaning 'smooth' and 'wrapMode' works.
