Muminul Islam ff4c8f7480 hypervisor: mshv: handle Special Debug Print VMG exit
Add handling for GHCB_INFO_SPECIAL_DBGPRINT VMG exit in the SEV-SNP
guest exit handler. This exit occurs when the guest sends debug print
requests through the GHCB interface.

Without this handler, SEV-SNP guests fail to boot when debug output
is triggered, such as when a debugger is attached to the guest image.

The handler acknowledges the exit without printing to avoid performance
degradation from frequent debug print requests.
