Reduces VALU usage in Q2RTX traversal by ~8%, though doesn't look

For Control we get a ~5% reduction in VALU usage, but similarly it
doesn't look like a bottleneck.

When multiview is used, the last pre-rasterization stage should export
the layer to the fragment shader. With GPL, the next stage is
implicitly FS.

When compiling the pre-rasterization stages with GPL, we can't know if
the fragment shader reads the primitive ID or the clip/cull distances
as inputs and we have to export them unconditionally.

When the fragment shader reads the viewport index as input and the last
pre-rasterization stage doesn't export it, it should be implicitly
zero (ie. first viewport). When the next stage is known, it's already
lowered in NIR, but with GPL we can't because we don't know if the FS
reads it. To fix this use AC_EXP_PARAM_DEFAULT_VAL_000.

When compiling the pre-rasterization stages we don't know the primitive
topology, but we still want to enable NGG culling for performance. To
achieve that, NGG culling is enabled unconditionally when the topology
is unknown and disabled dynamically for points or lines.

Optimizes code a tiny bit, and avoid the hack of encoding the root
node id in the low bits of the BLAS address in an instance node.
This is needed to adjust serialization/deserialization as the
instance address there has to be the base address, so this avoids
some wrapping/unwrapping.

Use pointer arithmetic from GL_EXT_buffer_reference2 to replace explicit
struct sizes. For that to work we also need to fix BDA alignment by setting
it to the smallest possible value (default is 16).
We could also replace the INDEX macro with a[b] operators, but that's actually
a change in behavior because a[b] always uses 64bit arithmetic.
