rtx: calculate maxVertex correctly

Browse Source 
after we've updated how brush index buffer references vertices to allow
for draw call coalescing ray tracing broke on amd.
this is because amd cards expect a correct value in
VkAccelerationStructureGeometryTrianglesDataKHR::maxVertex. make sure we
fill a correct value there.
