Take a vCPU directly instead of a VM+vcpu pair in all vCPU-scoped helpers
and ioctls.

Convert svm_nested_soft_inject_test to use vm_create_with_one_vcpu() and
pull the vCPU's ID from 'struct kvm_vcpu'.

Move the get/set part of the MP_STATE and GUEST_DEBUG helpers to the end
to align with the many other ioctl() wrappers/helpers. Note, this is not
an endorsement of the predominant style, the goal is purely to provide
consistency in the selftests.

Fold kvm_util_internal.h into kvm_util_base.h, i.e. make all KVM utility
stuff "public". Hiding struct implementations from tests has been a
massive failure, as it has led to pointless and poorly named wrappers,
unnecessarily opaque code, etc...
Not to mention that the approach was a complete failure as evidenced by
the non-zero number of tests that were including kvm_util_internal.h.

Add a KVM self-test that checks whether a nSVM L1 is able to successfully
inject a software interrupt, a soft exception and a NMI into its L2 guest.
In practice, this tests both the next_rip field consistency and
L1-injected event with intervening L0 VMEXIT during its delivery:
the first nested VMRUN (that's also trying to inject a software interrupt)
will immediately trigger a L0 NPF.
This L0 NPF will have zero in its CPU-returned next_rip field, which if
incorrectly reused by KVM will trigger a #PF when trying to return to
such address 0 from the interrupt handler.
For NMI injection this tests whether the L1 NMI state isn't getting
incorrectly mixed with the L2 NMI state if a L1 -> L2 NMI needs to be
re-injected.
