boot: zephyr: prefer swap move if scratch_partition not enabled 

With the exception of nrf targets BOOT_SWAP_USING_SCRATCH mode was
still the default algorithm.

Changing the preferred mode in cases where no scratch_partition is
defined will allow successfully building mcuboot for such boards w/o
the need for any board specific overlays.

If y, the BOOT_IMAGE_UPGRADE_MODE will default to using
"move" instead of "scratch". This is a separate bool config
