vgsp: m70 - restore the capture-exact FBMEM instance/ramfc (revert the m62 readback deviation)
The m62 sysmem-chunk instance/ramfc made the server's writes host-readable
(job done: FECS showed V7's instance loaded with VALID=1, TARGET=3 sysmem),
but the captured real lane uses FBMEM slices and the GR engine core's
context restore may require VIDMEM instance/RAMFC. Keep every fix
(R1/E2/m68 prefetch/m69 win0) and restore the capture shape.
