TdxValidateCfv is used to validate the integrity of FlashNvVarStore (PcdOvmfFlashNvStorageVariableBase) and it is not Tdx specific. So it will be moved to PlatformInitLib and be renamed to PlatformValidateNvVarStore in the following patch. And it will be called before EmuVaribleNvStore is initialized with the content in FlashNvVarStore.
