3c2966fa1b radv: rework dirtying scissors when the line width changes
The guardband state (part of scissors) needs to be re-emitted when
the line width changes. Given this is a dynamic state, it's not
necessary to look at the pipeline line width.

d88aba8946 radv: make sure to emit BREAK_BATCH when color write enable is dynamic
Color write enable can change CB_TARGET_MASK and emitting a BREAK_BATCH
seems needed for binning. Though, this was broken if this enable bit
changed dynamically for the same pipeline. Split the function to not
increase CPU overhead.

That shouldn't change anything for VS as LS (or as ES) and for
TES as ES because radv_vs_output_info is only used by the last
vertex stage. So, if we have TES+GS, radv_vs_output_info for TES
will be overwritten by GS. This allows to decouple the shader info
pass from other stages.

f75452918b ac/nir/ngg: support clipdist culling
Port from radeonsi.

Besides vertex position based primitive culling, clipdist
attribute can also be used to cull a primitive. Normally
it's used by fixed-pipeline, but when NGG we can treate it
as a culling condition to filter out invisible primitive
before fixed-pipeline.

There are two kinds of clipdist:
1. user define a clip plane explicitly by glClipPlane(),
   fixed-pipeline calculate with vertex position to get
   clipdist, then cull. This is the legacy way.
2. Now GLSL define gl_ClipDistance/gl_CullDiatance so that
   user can calculate clipdist in any way he like.

This implementation support both way.

1bdeb961bd ac/nir/ngg: add gs culling
Port from radeonsi.

Cull primitive after GS thread and before final vertex/primitive
export. GS culling is like VS/TES culling which read out saved
vertex positions of a primitive from LDS then call the primitive
culling algorithm to check whether it's visiable or not, only
passed primitives will be exported.

Unlike the VS/TES culling that read vertex index of a primitive
from VGPRs as shader args, GS will set a primitive complete flag
for each last vertex of a primitive in LDS, so that vertex thread
know the previous 1/2/3 vertex can form a primitive and do primitive
culling.
