gpu: nova-core: reserve vGPU WPR2 heap
GSP-RM needs a larger WPR2 heap when booting in vGPU mode. The heap size
is firmware-dependent, so it should come from the generated firmware
bindings instead of being open-coded in nova-core.
Pass the detected vGPU state into the framebuffer layout calculation. Keep
baremetal boots on the existing heap sizing path, and use the 570.144
vGPU default heap binding only when vGPU is enabled. The same state match
also sets the VF partition count, so disabled and invalid 0/1-VF states do
not enter the vGPU heap path.
