Mute HyperX QuadCast S at logon and sync Windows mute to it

Sets the mic's own hardware mute (USB Audio SET_CUR mute on feature
unit 6, via IDeviceTopology/IAudioMute) when it appears, and follows its
05 10 xx HID mute reports to keep the Windows endpoint mute in step.
Includes build/install/uninstall scripts and a read-only HID listener.
