OvmfPkg/TdxMailboxLib: Add NULL instance of TdxMailboxLib
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4172
TdxMailboxLib is designed only for TDX guest which arch is X64. This
patch set the VALID_ARCHITECTURES of TdxMailboxLib as X64.
Because in the following patches TdxMailboxLib will be included in
PlatformInitLib. While PlatformInitLib is imported by some X64 platforms
(for example AmdSevX64.dsc). So we need a NULL instance of TdxMailboxLib
which VALID_ARCHITECTURES is X64 as well. Based on this consideration
we design TdxMailboxLibNull.
