Mouse fix - fixes No mouse control when trying to run preinstalled catalina #766

[sickcodes]

As per @gilelias comment https://github.com/sickcodes/Docker-OSX/issues/766#issuecomment-2156706595

I introduced a bug with mouse on old versions by switching

-usb -device usb-kbd -device usb-tablet to -device qemu-xhci,id=xhci -device usb-kbd,bus=xhci.0 -device usb-tablet,bus=xhci.0

This PR reverts the Dockerfile to use in the launch script:

    && tee -a Launch.sh <<< '${XHCI_STRING:--usb -device usb-kbd -device usb-tablet} \' \

And adds runtime option for newer machines:

-e XHCI_STRING="-device qemu-xhci,id=xhci -device usb-kbd,bus=xhci.0 -device usb-tablet,bus=xhci.0"

Untested.
