[PATCHv4 06/14] x86/kexec: Keep CR4.MCE set during kexec for TDX guest

TDX guests are not allowed to clear CR4.MCE. Attempt to clear it leads to #VE. Use alternatives to keep the flag during kexec for TDX guests. The change doesn't affect non-TDX-guest environments. Signed-off-by: Kirill A. Shutemov Reviewed-by: Kai Huang ---
