Fix T96434: bad performance with viewport statistics and GPU subdivision
The subdivision is always recomputed on the CPU when displaying stats
if the mesh is animated which leads to bad performance.
This caches the subdivision topology counters from the draw code in the
mesh runtime and uses them for the viewport statistics.
