topology2: add second capture stream for DMIC0 for MTL topology

[jairaj-arava]

These changes adds a second stream for DMIC to the MTL Chromebook topology. The second stream can be used as a reference stream by the user. All the needed supporting changes were already merged via #6783.
Verified the functionality by simulataneously capturing data via both the streams and didn't see any issue in the recorded data as of now.

@jairaj-arava is there array of four DMIC for rt5682 ? or two ? If only two, we don't need to support 4 channel stream

@RanderWang for Chromebooks we always assume there are four mics, and then CRAS removes the channels that don't exist using the mapping found in the platform-specific UCM extensions. At the fimware/topology level we always expose 4 channels to reuse the same thing and not worry about hardware changes.

@jairaj-arava can you please have a look at the change in #7113? We are switching to using arrays and I'd like all new changes to follow that

@jairaj-arava array-support merged in #7113 so rebase will be needed

One DUT not run in https://sof-ci.01.org/sofpr/PR7085/build4015/devicetest/index.html test, but not relevant for this PR, so proceeding with merge.
