In Windows:

uses
  Windows;

procedure TForm1.FormCreate(Sender: TObject);
const
  ECM_FIRST = $1500;
  EM_SETCUEBANNER = ECM_FIRST + 1;
begin
  SendMessage(Edit1.Handle, EM_SETCUEBANNER, 0,
    LParam(PWideChar(WideString('My placeholder on Windows'))));
end;

I implemented this feature in an old project that I maintain, LazSolutions,
and it was cross-platform.
