Otherwise the wrong parent link might be set.
This kinda relies on waves being launched in order which tends to
be the case on AMD. To avoid the busy-wait loop waiting on stuff
from the same subgroup we do the actual processing in the body of
the loop. This can have performance implications but mostly in the
case we'd otherwise deadlock, so meh.

I need space ...
Furthermore, this only gets used during the build, and we can eat
the cost of generating the AABB a second time there.

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.

We only skipped the `accelerationStructureReference == 0` case
which could lead to reading uninitialized memory.
This patch introduces a NULL_NODE_ID constant and uses it
to handle inactive nodes properly.
I do not think, that this case is common in practice.
