[Regression] Can't add a hotkey to a custom control

[flexxxxer]

Describe the bug
Registration of hotkeys for controls that do not implement Avalonia.Input.IClickableControl is not possible.

To Reproduce
Example with working hotkey registration for custom type HotKeyedTextBox inherited from Avalonia.Controls.TextBox for Avalonia v0.10.21 and not working hotkey registration for custom type HotKeyedTextBox inherited from Avalonia.Controls.TextBox for Avalonia V11 here.

But in general:

1. Create custom control which not implementing Avalonia.Controls.TextBox or not inherits from Avalonia.Controls types which implements Avalonia.Input.IClickableControl (examples: Window, UserControl, TextBox, TextBlock, PathIcon, ListBox, etc).
2. Implement HotKeyProperty and HotKey like Avalonia.Controls.Buttons
3. Implement ICommandSource where in Command will be your hotkey logic (implementation of Avalonia.Input.IClickableControl not possible due protection level).

Expected behavior
Hotkey working.
