Linear PE has already shown to have some rough corner cases in the hardware
and also has performance implications. Add a debug option to allow to disable
the feature, so users can more easily check if some issue is caused by this
feature.

When linear rendering is used together with TS, the color tiles must be fully
contained in a single row of pixels. When wrapping around to the next row
TS gets confused and records wrong tile status information, leading to visual
corruption when the surface is resolved/decompressed.
The corruption can be fixed by increasing the stride alignment for linear
render targets, but that would break some existing use-cases, as some display
engines used together with Vivante GPUs currently don't support strides that
don't match the horizontal display resolution.
For now only enable linear PE rendering when the surface is properly aligned
already. This allows to use the optimization in a lot of common use-cases, but
falls back to the proven tiled rendering with subsequent resolve into linear
for the problematic cases.

The decision whether to use fast clear aka TS currently checks for two
feature bits: FAST_CEAR and MC20. We check for MC20, as TS on MC1.0 bypasses
the memory offset and we don't have any way to fixup the GPU address to
account for that. It could be done with some support of the kernel driver,
but then GPUs with MC1.0 are very rare to find these days, so not sure if we
are ever going to bother with that.
Instead of checking two separate feature bits to determine if TS can be used,
mask out the FAST_CLEAR bit from the features when MC20 isn't present. This
way we only have to check for a single feature bit.

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.

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.

Simplify: 64bit IO has been lowered by nir_lower_io with
nir_lower_io_lower_64bit_to_32, so no need to handle in the

Fix: we need to increase io_sem.location by base_offset for
correct gs_output_info.
radeonsi has different driver_location and io location, so
also change the output variable index to io location.

If we have neither, then we have to fall back to linear.
