Add Linux PacDrive + Libusb Drivers

[teejusb]

Largely originates from stepmania/stepmania#1479 so see that thread for context.

libusb-dev needs to be added to the build pipeline

[natano]

I think we could just always use libusb for all platforms. That way we could get rid of the dispatch mechanism and remove two of the files.

Maybe you'll be interested in simplified linux pacdrive backport. I tested it on stepmania: 5_1 branch.
https://github.com/jsirex/stepmania/tree/linux-pacdrive-5.1

Also, udev rule so no root required:

cat /etc/udev/rules.d/75-linux-pacdrive.rules
SUBSYSTEM=="usb", ATTRS{idVendor}=="d209", ATTRS{idProduct}=="1505", MODE="0666"
SUBSYSTEM=="usb", ATTRS{idVendor}=="d209", ATTRS{idProduct}=="1500", MODE="0666"

idProduct sometimes changes. I have couple devices.

I think I might delegate to @DinsFire64 and see if they have a preference on the implementation used for the Linux PacDrive

[jsirex]

I often have to backport this, so decided to simplify the implementation, because whole job had to be done here is just write a couple bytes to device via usb_control_msg. No need that complecated Driver -> UBSDriver -> PacDrive.

Also I made it optional via CMAKE.

However there aren't wire mapping configuration.

So feel free to use any approach, copy-paste/merge solutions.
I also tested this patch on stepmania 5.1 branch and confirm it works
