The last 12 bytes are always 0 for now. With this, all SHA1 functions
can be internally implemented as BLAKE3, so that we can switch everything
to BLAKE3 by only changing the implementation of the sha1 utility.

It is more efficient to compute the child index of the current node
inside the parent node and write the bounds when available. The previous
code could load up to 16 AABBs to compute the new ones. The new code
also only needs 1/7 of the previously used scratch memory. The new code
seems to be around 30% faster (0.5ms) in GOTG on a 6700XT.

Extracting from an SGPR could cause a wrong RegClass on
the operand which could later lead to selecting VOPD
instructions which falsely operate on the corresponding
VGPR.

RGP expects linear indexing across the number of counters/components.
Because a component can be used with different counters, its index
should be re-used when needed.

Implement a mitigation for VM faults caused by SMEM reading
out of bounds when using robust buffer access.
- Pad uniform and storage buffer allocations with a readonly VM page
- Clamp SMEM offsets that can potentially read past the next page

Implement a mitigation for VM faults caused by SMEM reading
from NULL descriptors.
In order to satisfy VKD3D-Proton's expectations on mutable
descriptors, we must do this in shader code, it is not
sufficient to use the address of a mapped BO when writing
null descriptors. It is not feasible to mitigate this
in VKD3D-Proton.

Map the first page of the same BO as read-only after the BO itself
in order to pad each BO with an extra page. This doesn't require
us to allocate any memory.
This is going to be used for a HW bug mitigation.

The pass implements two mitigations for the GFX6-7 SMEM bug:
1. To mitigate VM faults by NULL descriptors:
Make sure that SMEM buffer loads always access a mapped BO.
Use either the descriptor BO (or compute scratch BO),
or otherwise use the zero-filled BO in their place.
2. To mitigate VM faults by OOB robust buffer access:
Add an instruction to clamp the offset source to the
num_records field of the descriptor. It will be still
out of bounds, but the VM fault can be completely mitigated
if the driver adds a padding to each memory allocation.

On GFX6-7, SMEM instructions access memory when num_records == 0
or offset >= num_records, which causes VM faults when reading a
page that isn't mapped.
