[Lazarus] Send keys to visual component

[Felipe Monteiro de Carvalho]

IntfUtf8KeyPress will tell LCL that your control received a keypress
message, and thus it will call your OnUTF8KeyPress handler, but it
won't really emulate a key press on the control.

To do that I would try using SendMessageW to send a WM_CHAR (or some
other message) to the control. docs here:

We have a partial implementation of SendMessage on LCLIntf, but I
would bet it isn't capable of emulating key pressing everywhere.

The Windows version of SendMessage obviously only works for Windows
and Windows CE.
