Builds a EFI_HOB_TYPE_FV3 HOB.
This function builds a EFI_HOB_TYPE_FV3 HOB.
It can only be invoked during PEI phase;
for DXE phase, it will ASSERT() since PEI HOB is read-only for DXE phase.
If there is no additional space for HOB creation, then ASSERT().
@param BaseAddress The base address of the Firmware Volume.
@param Length The size of the Firmware Volume in bytes.
@param AuthenticationStatus The authentication status.
@param ExtractedFv TRUE if the FV was extracted as a file within
another firmware volume. FALSE otherwise.
@param FvName The name of the Firmware Volume.
Valid only if IsExtractedFv is TRUE.
@param FileName The name of the file.
Valid only if IsExtractedFv is TRUE.
