vgsp: srv_ctxcommit mode 2 (V6 client combined init+VA entry)
Make gsp_phys_rmcall_srv_ctxcommit an int mode: 1 (default) = map +
INITIALIZE_CTX + UVM-shape VA-only promote; 2 = V6 client variant, no
INITIALIZE_CTX and one combined PA+VA MAIN entry with bInitialize=1 and
bNonmapped=0 so the first ctxsw initializes from the golden image; 0 = pure
server-managed. Lets the next supervised cycle bisect both entry shapes
without a rebuild. Build clean; not hardware-tested (GPU wedged).
