[outdated] ControllerManagement for iOS

[J0EK3R]

I've added the missing ControllerManagement for iOS, as it's already implemented for Android and Windows.

Then, I've removed the generic parameter of GameControllerServiceBase to handle different types of input devices/controllers, such as MCPServer ;). IGameController is now used instead.

And I've cleaned up the code:

• Removed unused properties of IGameController and GamepadControllerBase
• Removed unused code

Pull Request Overview

This PR implements ControllerManagement for iOS to bring feature parity with Android and Windows platforms. It refactors the GameControllerServiceBase to use IGameController directly instead of generic types, enabling support for different controller types like MCP servers.

• Adds complete iOS GameController implementation with proper device management
• Removes generic constraint from GameControllerServiceBase to handle diverse controller types
• Cleans up unused properties and code across the codebase

Why is type of GamepadController needed to be defined for TryRemove? What is the benefit of such change, if it has to be specified here?

[J0EK3R]

It's because we lost the generic in the base class - it's just the interface IGameController now

    /// <summary>
    /// Collection of available gamepads having <see cref="IGameController.ControllerId"/>
    /// </summary>
    private readonly List<IGameController> _availableControllers = [];

But to distinguish the controllers we neet to handle the real type to be able to access properties not defined in the interface.

If there is another remove-event for another controller type to handle - i.e. for the McpServer ;) - the generic paramater of TryRemove<> would be that special type of controller:

    private void McpServerRemoved(object? sender, McpServer e)
    {
        lock (_lockObject)
        {
            // ensure stopped in UI thread
            _ = _mainThreadService.RunOnMainThread(() =>
            {
                if (TryRemove<McpServerController>(x => x.ControllerDevice is McpServer, out var controller))
                {
                    _logger.LogInformation("McpServer has been removed");
                }
            });
        }
    }

I d not like this desgin as:

• it enforces hard coupling of MCP server to controller service for each platform

* additionally it seems to me in your follow up (#165), MCP platform inplementations are nearly the same. Is it?

Shortly said, it should be done differently. May be there might be some game controller providers, which are providing different types of game controllers, the gamepad ones, MCP ones. Just a quick idea.

[J0EK3R]

Yes, if I understood you correctly, I see it that way too.
It would be a clean solution if there were a central instance that manages all types of input devices and handles event signaling (gamepad 🕹️ events, gyro events, mcp server events, etc.).
Then there should be providers for the different types of input devices that register and deregister the input devices with the central instance und call the event invoking methods...

If I find some time these days I'll suggest an implementation of that.
