This performance counter test verifies that re-binding the same
two buffers repeatedly doesn't allocate new descriptor sets. Currently
the test fails because we don't cache descriptor sets for UBOs.

Covers equivalent code patterns in Asphalt 9.

Reorganizes the perf counters collected for the program objects. Now
they are per-frame reset instead of cumulative. This tracking is now
consistent for the different counter types. In the future we can add
cumulative tracking for all per-object and global perf counters.
