PC Microphone Passthrough for Android Device

[Asfu-Ahmed]

I'd like to suggest adding support for using the PC's microphone as the connected Android device's microphone while using QtScrcpy.

This would allow Android apps (voice chat, calls, voice recording, AI assistants, etc.) to use the PC's microphone instead of the phone's built-in mic, making the desktop experience much more seamless.

If technically feasible, I think this would be a valuable feature for many users.
