[Linux/MacOS] Further Wiimote changes for parity with Windows

[capitalistspz]

(Edit) Changes:

• Change Wiimote comparison so that controllers cannot be mistaken as others, so that using multiple Wiimotes is actually possible
• Use non-blocking reads to reduce input lag for extra Wiimotes
• Enable nunchuk motion
• Enable the Wiimote settings menu

Original Comment:

Now there should be no way that one controller is mistaken as being another connected controller

This pr fixes my second wii remote not being able to connect to Cemu using my standard Bluetooth dongle. The only remaining issue for me using Wiimote Api on Linux is that my Nintendo RVL-CNT-01-TR pointer lags. There is a noticeable delay when pointing and my remotes seem to disconnect randomly. My standard wii remote plus RVL-CNT-01, the pointer seems to work fine in Wii Party U when tested.

I ran Cemu with Logging turned on for the input API and this is what I get:

Not sure what is causing the input lag and disconnects. All I see is WPADProbe(0) KPADReadEx(0, 0x10) Blinking while I wait for reconnects. Hope this helps.

EDIT: It seems this input lag is a known issue. #636

Windows is unaffected in my testing.

Because I originally had reads set as blocking, I'm pretty sure that the second controller would only be read from when the first controller completed an actual read, whoops

I can confirm now that this pr fixes all my issues. Thank you! :)

The settings menu works for me now. I sincerely apologize if this is the wrong place to post this, but I noticed in my testing that Wii Sports Club, motion and pointer controls do not work.

I also noticed that the value after the zero in vpad.VPADRead(0, is changing every half second. That does not happen in Wii Party U (a game where motion and pointer controls work). I dont know if that has anything to do with it.

No idea about the pointer, but motionplus (which is required by Wii Sports Club) doesn't work on Cemu right now

Anything to do with VPAD is related to the Wii U Gamepad, so I don't think those reads are anything to do with the motion/pointer functionality of the Wiimote
