OvmfPkg: Add IntelTdx.h in OvmfPkg/Include/IndustryStandard 

RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429

IntelTdx.h defines the defition used by TDX in OvmfPkg:
 - Mailbox related defitions,such as the data structure, command code,
   AP relocation defitions.

See Table 5.44 Multiprocessor Wakeup Mailbox Structure in below link.
