/**
  Fills a target buffer with a value that is size UINTN, and returns the target buffer.

  This function fills Length bytes of Buffer with the UINTN sized value specified by
  Value, and returns Buffer. Value is repeated every sizeof(UINTN) bytes for Length
  bytes of Buffer.

  If Length > 0 and Buffer is NULL, then ASSERT().
  If Length is greater than (MAX_ADDRESS - Buffer + 1), then ASSERT().
  If Buffer is not aligned on a UINTN boundary, then ASSERT().
  If Length is not aligned on a UINTN boundary, then ASSERT().

  @param  Buffer  The pointer to the target buffer to fill.
  @param  Length  The number of bytes in Buffer to fill.
  @param  Value   The value with which to fill Length bytes of Buffer.

  @return Buffer.
