wined3d: Add support for shader model 3.0 I/O registers.

SM 3.0 can pack multiple "semantics" into 12 generic input/output registers.

To support that, define temporaries called IN and OUT, and use those as
the output registers. At the end of the vshader, unpack the OUT temps
into the proper GL variables. At the beginning of the pshader, pack the
GL variables back into 12 IN registers.
