vgsp: m83 - host-readable sysmem error notifier for the RM's channel-error records
NV_PGRAPH_EXCEPTION reads 0x01000000 (GPC) with EXCEPTION1 GPC1:0=0b11 at the
QMD activation; the fault record the engine writes goes to the channel's error
notifier, which is server FBMEM today and unreadable. gsp_phys_rmcall_gr_notifier_sys=1
registers a host sysmem chunk as the hObjectError memory object and carries it
in the channel's errorNotifierMem with the SYS aperture, so the RM's
asynchronous channel-error report is dumped in the launch post-mortem
(the m35 lane still uses the captured substitute object shape).
