This is v10 of the TDX selftests.

This series is based on v6.17-rc4 and has a dependency on
"KVM: TDX: Force split irqchip for TDX at irqchip creation time" [1]

Changes from v9 [2]:
- Rebased on top of v6.17-rc4.
- Addressed the comments from v9.
- Removed special handling for split irqchip in the test code in favor
  for the kvm fix in [1].
- Removed outdated support for VM memory not backed by guest_memfd.
- Split "KVM: selftests: Hook TDX support to vm and vcpu creation" into
  4 separate patches.
