r600g: fixup states generation in winsys.

The current states code had an unhealthy relationship between
that had to somehow magically align themselves, editing either
place meant renumbering all states after the one you were on,
and it was pretty unapproachable code.

This replaces the huge types structures with a simple type + sub
type struct, which is keyed on an stype enum in radeon.h. Each
stype can have a per-shader type subclassing (4 types supported,
PS/VS/GS/FS), and also has a number of states per-subtype. So you
have 256 constants per 4 shaders per one CONSTANT stype.

The interface from the driver is changed to pass in the tuple,
(stype, id, shader_type), and we look for this. If
radeon_state_shader ever shows up on profile, it could use a
hashtable based on stype/shader_type to speed things up.
