app: overlays: disable ADSP logging backend for IPC4 targets 

Each logging backend has an overhead and we don't need two backends
writing to SRAM windows, so disable ADSP and keep MTRACE for IPC4
targets. Other targets will continue to use ADSP backend.

Due to a limitation in upstream Kconfig options, this change
will force a change in timestamp formatting as disabling ADSP
will disable CONFIG_LOG_BACKEND_FORMAT_TIMESTAMP=y. Mitigate
this by enabling CONFIG_LOG_OUTPUT_FORMAT_LINUX_TIMESTAMP=y.
