[Issue]: Pressing the win key on an external keyboard does not work

Describe the bug

May I ask if I have turned on Sunshine on my computer and then connected to my computer using Moonlight on my tablet, but how can I make the win key (actually the key code is the meta_left key) of the keyboard work properly? I know Sunshine provides Alt_ The right key replaces the win key, but it cannot use a combination of win keys.

It's not that Android ate the win key, but rather that the Moonlight software itself didn't listen to it (I tried changing Moonlight's code), so no matter how you press the win key, Moonlight won't transfer the win key. But I found a software that can listen to this win key, unfortunately I don't know how it works. You can refer to it and perhaps implement this function for Moonlight.

#The important point is that this seems to be unrelated to the computer and Sunshine, but rather the Moonlight software itself did not listen to this win key

Steps to reproduce

1. Turn on Sunshine on the computer.
2. Connect the Android tablet to an external keyboard (Bluetooth or wired).
3. Connect to the computer using Android tablet moonlight.
4. During the process of controlling the computer, pressing the win key does not respond and the computer cannot use the combination keys of win.

Begin by reproducing the missing meta_left event with an external keyboard on Android 10–12 while connected through Moonlight, then trace the Android keyboard-input handling. Use the KeyMapper project linked in the issue as a comparison point. Done means the Windows key is forwarded and Windows-key combinations work on the server.
