HID: Add Mapping for System Microphone Mute

[ Upstream commit 2d60f9f4f26785a00273cb81fe60eff129ebd449 ]

HUTRR110 added a new usage code for a key that is supposed to
mute/unmute microphone system-wide.

Map the new usage code(0x01 0xa9) to keycode KEY_MICMUTE.
Additionally hid-debug is adjusted to recognize this keycode as well.
