+ Builds a EFI_HOB_TYPE_FV3 HOB.

+ This function builds a EFI_HOB_TYPE_FV3 HOB.

+
+ If there is no additional space for HOB creation, then ASSERT().

+ @param AuthenticationStatus The authentication status.
+ @param ExtractedFv TRUE if the FV was extracted as a file within

+ @param FvName The name of the Firmware Volume.
+ Valid only if IsExtractedFv is TRUE.
+ @param FileName The name of the file.
