vgsp: m93 - dump the launch-time instance SC/PDB words (w126..131, w166..173)
The m90/m91 decode pinned the SM I-fetch failure to WARP_ESR MMU_NACK at
the window-0 shadow VA, while everything FE-side resolves the same small-PT
line. The SC array (RAMIN words 166+: VALID mask, then per-VEID
SC_PAGE_DIR_BASE LO/HI/flags) is the page directory the SMs' walk is
expected to use; log it raw at launch time so the next cycle shows which
base/target/flags the server actually programmed (and whether it is the
module VASPDB root).
