BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4172

In the following patches TdxMailboxLib will be included in
PlatformInitLib. While PlatformInitLib is imported by some IA32/X64
platforms (for example AmdSevX64.dsc). So TdxMailboxLibNull is added in
those platforms which don't support TDX feature.
