Now that we always use LBVH this is not useful anymore.
In the future, when we have more options, we will use a different approach.

Moves radv_acceleration_structure from radv_private to radv_acceleration_structure.
If we already have a acceleration structure header, we can also use it instead of radv_private.

cull_small_primitive will now allow the caller to pass an
SSA def that it will use to determine if the primitive was
initially rejected.
This allows ACO to remove an s_branch instruction from every
NGG culling shader.

The previous code checked all_w_positive in the if condition.
Instead, always execute the bbox culling code and include
all_w_positive at the end.
We assume checking in the if is not beneficial because it's
very unlikely that there is no primitive in a wave whose W are
not all positive.
This allows moving other things to the condition
in the next commit.

This extension introduces a new layout which allows applications
to both render and sample from the same image inside the same draw
(aka. feedback loops).
Previously, the GENERAL layout was used and this introduced some
rendering artifacts because the hw can't read&write DCC/HTILE for
the same image, and we try to keep it compressed on GFX10+.
This helps fixing corruption with D3D9 and RPCS3 games which
are candidate for feedback loops.
