This makes the names match the recommended names in the ALSA UCM header: https://github.com/alsa-project/alsa-lib/blob/f1fa7ea07768bd5dbe15462ef734b28380a12a43/include/use-case.h#L112-L144
I'm not deduplicating the UCM files between m3 and m0 as I may not always be able to test changes to m3, and I'd rather have a an outdated configuration for m3 than a broken one.
