This will enable large code removal.
shader->config.lds_size is now always computed the same as ACO except for
compute shaders.
We have to add a new 8-bit user SGPR bitfield called
GS_STATE_GS_OUT_LDS_OFFSET_256B, which contains the offset
that was previously set by the relocation.
Since the offset must be a multiple of 256, we have to add padding
to the LDS size computation to make sure the alignment to 256 for the ESGS
LDS size doesn't cause us to exceed the maximum LDS size.

This increases primitive throughput when packing reduces the number
of pos exports due to holes in clip and cull distance arrays that could be
punched out by nir_opt_clip_cull_const. This applies to all chips.

This increases primitive throughput for all hw with NGG if the shader
culls and the removal of cull distances reduces the number of position
exports.

It will be different between NGG and legacy because NGG with culling
will not export cull distances.
The number of position exports could also be gathered from final NIR
to reduce logic duplication.

This is very useful for increasing raw primitive throughput for GS
(mostly just RDNA 2), increasing raw primitive throughput with clip
and cull distance outputs when they actually cull anything (RDNA 1-4),
and reducing attribute store bandwidth usage (RDNA 3-4).
It will also replace fixed-func culling against cull distances when
culling in the shader is enabled, which will increase primitive throughput
even further.

When culling is enabled for GS, we will need ES, GS, and FS in this
function at the same time.

Clip and cull distance outputs decrease primitive throughput, so culling
against them in the shader has even more benefit than other culling
options.

This simplifies shader info in drivers by returning GSVS emit sizes from
ac_nir_lower_legacy_gs. The pass knows the sizes, so drivers shouldn't
have to determine them independently.
This also makes the values more accurate because both drivers were
computing the GSVS emit sizes inaccurately and had redundant fields
in shader info. RADV had a lot of redudancy there.
