ASoC: SOF: Intel: Add support for MeteorLake (MTL)

Add platform abstraction for the Meteor Lake platform.

This platform has significant differences compared to the TGL/ADL
generation: it relies on new hardware using the code name 'ACE' and
only supports the INTEL_IPC4 protocol and firmware architecture based
on the Zephyr RTOS
