Routine Description:

  Finds a token value given the section and token to search for.

Arguments:

  InputFile Memory file image.
  Section   The section to search for, a string within [].
  Token     The token to search for, e.g. EFI_PEIM_RECOVERY, followed by an = in the INF file.
  Instance  The instance of the token to search for.  Zero is the first instance.
  Value     The string that holds the value following the =.  Must be MAX_LONG_FILE_PATH in size.

Returns:

  EFI_SUCCESS             Value found.
  EFI_ABORTED             Format error detected in INF file.
  EFI_INVALID_PARAMETER   Input argument was null.
  EFI_LOAD_ERROR          Error reading from the file.
  EFI_NOT_FOUND           Section/Token/Value not found.
