Implement offset lowering by calculating implicit LOD using coordinate derivatives (ddx/ddy)

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.

It has been implemented and works for PS outputs already.
The lowering callback needs 2 variants because we can't access
pipe_screen from it. The callback is rewritten to be more general.
We also need to do nir_clear_mediump_io_flag for any outputs we don't
lower because the mediump flag might prevent optimizations if it's not
cleared.

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 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.
