bootutil: optionally use flash_area_get_sectors()

Add a typedef which lets us use flash_sector or flash_area to contain
the sectors within the boot_data global. When
MCUBOOT_USE_FLASH_AREA_GET_SECTORS is defined, this is struct
flash_sector.

Also add struct boot_loader_state accessors to handle this case, and
make the appropriate changes to where the sectors are allocated to use
the new typedef.

Finally, ensure MCUBOOT_USE_FLASH_AREA_GET_SECTORS is defined in the
Zephyr Makefile, since flash_area_get_sectors() is already provided
there.

This lets mcuboot users convert to the new flash API gradually.
