Multi Controller Support tvOS

[steilerDev]

Describe the bug
I'm trying to connect multiple DualShock controller to my Apple TV in order to play local multiplayer mode on my Sunshine Host. At the moment, when connecting both controllers only one HID device shows up on the host and both controllers are using the same "channel".

On iPadOS multiple controllers connected to the iPad result in multiple HID devices on the host. Additionally there is a "Multi-Controller Mode" on the iPad settings that I'm missing on tvOS

Steps to reproduce
Connect multiple controllers - try to play a game with local multiplayer

Affected games
Single controller input works without an issue - tested Tekken through Steam on iPad to validate that it is working

Moonlight settings (please complete the following information)

• Have any settings been adjusted from defaults?
  No
• If so, which settings have been changed?
• Does the problem still occur after reverting settings back to default?

Gamepad-related issues (please complete if problem is gamepad-related)

• Do you have any gamepads connected to your host PC directly?
  No
• If gamepad input is not working, does it work if you use Moonlight's on-screen controls?
  Working with a single controller - second controller input also works, but not as a separate device
• Does the problem still remain if you stream the desktop and use https://html5gamepad.com to test your gamepad?
  Yes

I'm running into this issue as well. Streaming multiplayer games to the TV would be perfect if this worked!

On tvOS the setting that enables multipleControllers is named Automatic Game Controller Detection.
