tgsi: pass a shader type to the machine create and clean up.

There was definitely bugs here mixing up the PIPE_ and TGSI_ defines,
hopefully they didn't cause any problems, since mostly it was special
cases for GEOMETRY.

This clarifies at shader machine create what type of shader this
machine will execute. This is needed also for compute shaders where
we don't want to allocate inputs/outputs.
