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.
