ALSA: hda/realtek: Add micmute LED quirk for Acer Aspire A315-44P

The mic-mute LED on the Acer Aspire A315-44P (subsystem ID 0x10251640)
does not light up when the microphone is muted. The LED is connected to
GPIO3 of the Realtek ALC256 codec.

Add a quirk entry using ALC256_FIXUP_ACER_SFG16_MICMUTE_LED, which
configures GPIO3 (bitmask 0x04) as the micmute LED, identical to
the Acer Swift SFG16.

Tested by manually sending HDA verb commands directly to the codec
and verifying that GPIO3 drives the LED while GPIO1 and GPIO2
do not.
