[CK Tile Engine] Daily tier sampling for tile engine GEMM
 (#7311)

Summary
- Replace uniform random instance sampling (random.shuffle) with
scrambled Sobol + Latin Hypercube + maximin space-filling
sampling, per the Tile Engine Benchmark Sampling RFC
- Add op-weighted budget allocation via new
TILE_ENGINE_SAMPLING_TIER=daily CMake knob that auto-distributes 8,000
instances across
ops proportional to registered weights in op_weights.json
  - Emit chosen_instances.json manifests for reproducibility tracking
- Consolidate 5 copies of sampling logic into single _apply_sampling()
method on the base class
Jenkinsfile changes
Replace per-op -D *_MAX_INSTANCES=250 with single -D
TILE_ENGINE_SAMPLING_TIER=daily in gfx942/gfx950/gfx1201 stages. Budget
  auto-distributes (8000 total per GPU target).
