Made taskbar button follow main form monitor (Windows)

[shole]

I have multiple monitors and by default transgui does not transfer taskbar button when used on a secondary monitor. There are also these two issues mentioning the problem. https://github.com/transmission-remote-gui/transgui/issues/1299 https://github.com/transmission-remote-gui/transgui/issues/1056

I resolved the issue with the simple suggestions in some of the linked forum articles in the issue threads. https://forum.lazarus.freepascal.org/index.php?topic=24926.0 This allows taskbar button to move onto other monitors. It's not perfect and sometimes I need to maximize and restore the window for the switch to happen, but at least now it's possible, while before it never happened.

On compilation I get the warning Warning: (5044) Symbol "MainFormOnTaskBar" is not portable. I don't know what the side effects of that are, so I wrapped the call in {$ifdef windows} just in case.
