D3D12: Avoid re-binding sampler tables.

Skip re-binding samplers since sampler heap
allocations are cached and the pipeline would
redundantly get set every draw. This is
particularly important for draw heavy scenarios.

After the change:
+3% in RendererPerfTest/1.* via SkiaDawn
+100% for Forest Demo FPS (55ms vs 28ms)
