ALSA: hda/realtek: Fix headset mic on ASUS Zenbook 14 UX3405MA

The ASUS Zenbook 14 UX3405MA uses an ALC294 codec with CS35L41
amplifiers over SPI. The existing quirk for this model only configured
the amplifiers, leaving the headset microphone on the combo jack
non-functional.

Introduce a new fixup that configures pin 0x19 as headset mic input
and chains to ALC245_FIXUP_CS35L41_SPI_2 to preserve speaker
functionality.

Similar to the fix done for the UM3406HA in commit 018f659753fd
("ALSA: hda/realtek: Fix headset mic on ASUS Zenbook 14").
