[GIT PULL] KVM: Selftests changes for 6.12

[Sean Christopherson <seanjc@google.com>]

As mentioned in the cover letter, the tools/testing/selftests/kvm/.gitignore
change will conflict with the s390 pull request.  Easiest solution should be to
just take my changes (they're a strict superset).

The other notable selftests related change isn't part of this pull request.  I
posted a mini-series to use the canonical $(ARCH) paths for KVM selftests
directories[*], e.g. arm64 instead of aarch64.  My plan is to send a v2 after
all the arch pull requests are merged and try to squeeze it into the back half
of the merge window (I kinda forgot about LPC and KVM Forum, but I'm crossing
my fingers here will be minimal conflicts).

  KVM: selftests: Verify single-stepping a fastpath VM-Exit exits to userspace (2024-09-09 20:12:12 -0700)

----------------------------------------------------------------
KVM selftests changes for 6.12:

 - Fix a goof that caused some Hyper-V tests to be skipped when run on bare
   metal, i.e. NOT in a VM.

 - Add a regression test for KVM's handling of SHUTDOWN for an SEV-ES guest.

 - Explicitly include one-off assets in .gitignore.  Past Sean was completely
   wrong about not being able to detect missing .gitignore entries.

 - Verify userspace single-stepping works when KVM happens to handle a VM-Exit
   in its fastpath.

 - Misc cleanups
