vgsp: m96 - gr_pte_kind: set the Turing v2 PTE KIND on the window-0 shadow pool
UVM's Turing PTE maker sets KIND=GENERIC_MEMORY (0x06) in PTE bits 63:56
because PITCH no longer exists on Turing (uvm_turing_mmu.c:32-34,106;
NV_MMU_PTE_KIND_GENERIC_MEMORY=0x06, NV_MMU_VER2_PTE_KIND=63:56). Our
shadow PTEs encode kind=0. The SM I-fetch refuses the kind-0 PTE with
MMU_NACK while the FE tolerates it, so gr_pte_kind (default 0) selects the
KIND for the window-0 pool. Also log the VASPDB root DMA at
SET_PAGE_DIRECTORY time (settles whether the SC PDB the server programs is
our chunk).
