vgsp: golden-exec shape bisection + fwclient per-entry promotion + pool-VA stall fix

- Mode 28 golden execution lane behind gsp_phys_rmcall_gr_promote=28 with a
  shape bitmask (gsp_phys_rmcall_golden_exec_shape: ring / entries=8 / sysmem
  USERD / USERD size / hObjectBuffer=VAS / skip replay TURING_A) and a USERD
  control-offset helper. Finding: the RM-managed golden channel hangs any GR
  object construct (-110, no assert) as soon as client submission wiring
  (ring or sysmem USERD) is attached, so only the captured server-owned shape
  constructs; the machinery is kept for future wiring ideas.
- fwclient mask bit 11 (0x800): send each non-MAIN FWCLIENT promote entry as
  its own one-entry control and continue past refusals. V6 acceptance matrix:
  PM, PATCH, PRIV_ACCESS_MAP, UNRESTRICTED_PRIV_ACCESS_MAP accepted,
  FECS_EVENT refused 0x1f.
- fwclient mask bit 12 (0x1000): golden9 VA-only global bookings (BUNDLE_CB,
  PAGEPOOL, ATTRIBUTE_CB, RTV_CB_GLOBAL) accepted on V6; bits 13/14
  (0x2000/0x4000): FECS PA-only (refused 0x1f) and FECS VA-only (accepted).
- gsp_phys_rmcall_srv_main_ignore: ignore a server-reported MAIN in the
  srv-ctx commit and force the client INITIALIZE_CTX + VA-only fallback.
- gsp_sema_service: pool semaphores never fall back to the learned map; queue
  the absolute release via svc_pending_add until svc_pool_pa_resolve
  succeeds, and judge pool slots through the verified resolver in
  svc_apply_pending and the release decode (UVM registration stall fix).
