KVM: TDX: Disable support for TSX and WAITPKG

Browse source

Support for restoring IA32_TSX_CTRL MSR and IA32_UMWAIT_CONTROL MSR is not
yet implemented, so disable support for TSX and WAITPKG for now.  Clear the
associated CPUID bits returned by KVM_TDX_CAPABILITIES, and return an error
if those bits are set in KVM_TDX_INIT_VM.
