sof-soundwire: rt711-sdca: add Headset Mic Switch to Headset sequences

No sound captured in headset mic through jack on Dell Precision 5480, Ubuntu 24.04.4 LTS kernel version 6.17.0-20-generic

Headset Mic Switch is a DAPM gate that must be enabled to connect the
headset microphone input to the SoundWire capture pipeline. Without it
the mic path is powered down regardless of the FU0F Capture Switch state,
producing silence.

Add Headset Mic Switch on/off to Enable/DisableSequence, matching the
pattern already used for Headphone Switch in the Headphones device.
