vgsp: V6 client-owned ctx-buffer VA commit path (srvctx)
Source-confirmed: with the SKIP_CTXBUFFER_ALLOC channel flag the server does
not allocate MAIN, does not map/book it, and its internal init/promote
helpers return early for KMD virtual contexts. The client therefore owns the
buffer. When no server MAIN is reported on a V6 channel, map the prepared
client MAIN at the ladder ctx VA (sysmem PTEs), send GPU_INITIALIZE_CTX to
install the memdesc, then the UVM-shape VA-only promote; with no server
pre-booking the vaListSetManaged gate should pass and the per-buffer commit
program the engine context pointer. V5 keeps the historical PA-only
fallback. Build clean; not hardware-tested (GPU wedged).
