[nrfconnect][ota] Change image checking condition for OTA. (#28983)

If we want to confirm the new firmware update in the AppTask Init
method we cannot rely on the imageProcessor. Instead, for the nRF53
target we should check if the image has been confirmed already,
and if not, confirm it, for targets other than nRF53
we should use the  mcuboot_swap_type function to verify whether
the swapping type is equal to REVERT before verifying the image.
