OvmfPkg/TdxDxe: Change MadtMpWk->MailBoxVersion from 1 to 0 

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4527

According to ACPI 6.5 (https://uefi.org/specs/ACPI/6.5/05_ACPI_Software
_Programming_Model.html?highlight=mailboxversion#multiprocessor-wakeup-
structure) the MailBoxVersion is 0.

This patch changed MadtMpWk->MailBoxVersion from 1 to 0 to fix the error.
