  Log a formatted console message.

  This is not specific to this shell command but scoped so to prevent global
  name conflicts.

  The hex dump is split into lines of 16 dumped bytes.

  The full hex dump is bracketed, and its byte ascii char also print.
  If the byte value is not an ascii code, it will print as '.'

  @param[in] Offset            Offset to be display after PrefixFormat.
                               Offset will be increased for each print line.
  @param[in] Data              The data to dump.
  @param[in] DataSize          Number of bytes in Data.
