phase(N.5) Task 6 fixup: log symmetry + Silk extension shortcut

Browse source 
Code quality review caught:
- Silent failure when ARB_bindless_texture absent — the && short-circuit
  meant the most common fallback case (no bindless on the GPU) had no
  log, while ARB_shader_draw_parameters absent did log. Restructured to
  three nested ifs so each failure path logs symmetrically.
- Redundant `bindless is not null` guard removed (TryCreate's non-null
  guarantee covers it; the nested-if structure makes this implicit).
- HasShaderDrawParameters in BindlessSupport.cs replaced its manual
  GL_NUM_EXTENSIONS scan with `gl.IsExtensionPresent(...)` — same
  pattern WB uses, less code.
