This is v11 of the TDX selftests.

This series is based on v6.17-rc7

Changes from v10 [1]:
- Rebased on top of v6.17-rc4.
- Addressed minor comments from v10.
- Removed code for setting up X86_CR4_OSXMMEXCPT which is not needed for
now.
- Added call to vm_tdx_load_common_boot_parameters() in "KVM: selftests:
Call TDX init when creating a new TDX vm" which was accidentally
dropped between v9 and v10 due to code refactoring
