Re: [PATCH v12 04/23] KVM: selftests: Expose function to allocate guest vCPU stack

TDX guests' registers cannot be initialized directly using vcpu_regs_set(), hence the stack pointer needs to be initialized by the guest itself, running boot code beginning at the reset vector.

Expose the function to allocate the guest stack so that TDX initialization code can allocate it itself and skip the allocation in vm_arch_vcpu_add() in that case.
