Report the information for a new discoveried FV in unknown format.
If the EFI_PEI_FIRMWARE_VOLUME_PPI has not been install for specifical FV format, but
the FV in this FV format has been discoveried, then the information of this FV
will be cached into PEI_CORE_INSTANCE's UnknownFvInfo array.
Also a notification would be installed for unknown FV format guid, if EFI_PEI_FIRMWARE_VOLUME_PPI
is installed later by platform's PEIM, the original unknown FV will be processed by
using new installed EFI_PEI_FIRMWARE_VOLUME_PPI.
@param PrivateData Point to instance of PEI_CORE_INSTANCE
@param Format Point to the unknown FV format guid.
@param FvInfo Point to FvInfo buffer.
@param FvInfoSize The size of FvInfo buffer.
@retval EFI_OUT_OF_RESOURCES The FV info array in PEI_CORE_INSTANCE has no more spaces.
@retval EFI_SUCCESS Success to add the information for unknown FV.
