anv: Handle VkAccelerationStructureBuildRangeInfoKHR::transformOffset

Browse source 
Previously it was not actually handled. This meant that all geometries
with the same transform buffer were using the same (first) transformation
matrix.

Fixes: f3ddfd81 ("anv: Build BVHs on the GPU with GRL")
Closes: https://gitlab.freedesktop.org/mesa/mesa/-/issues/7575
