app: Enable DTS partitions
Replace Partition Manager with DTS partitions. Added overlay-trace-backend.overlay - Adds sram partition for traces - Moves application non-secure sram partition Added overlay-carrier.overlay - Adds NVS flash partition for Carrier library Added overlay-disable-b0.overlay - Disables B0 flash partition - Moves MCUboot and application flash partitions Added overlay-full-fota.overlay - Enlarges flash and sram partitions for TF-M - Adds flash partitions for TF-M ITS, PS, and non-volatile counters - Moves application flash and sram partitions - Trace sram partition enabled by default Signed-off-by: Markus Lassila <markus.lassila@nordicsemi.no>
