  The ExtractSection() function processes the input section and

  OutputBuffer is just updated to point to the start of the
  section's contents. Otherwise, *Buffer must be allocated
  from PEI permanent memory.

  @param This                   Indicates the
                                EFI_PEI_GUIDED_SECTION_EXTRACTION_PPI instance.

                                the new section stream.
  @param InputSection           A pointer to the input buffer, which contains
                                the input section to be processed.
  @param OutputBuffer           A pointer to a caller-allocated buffer, whose
                                size is specified by the contents of OutputSize.
  @param OutputSize             A pointer to a caller-allocated
