This PR adds support for new MCUboot mode: Direct XIP without revert.
The option with revert was already supported in 1.7.2.
The difference between with and without revert is, that without revert there's no Test or Confirm command.
Also, like in case of Direct XIP with revert the image comes in 2 binaries, compiled for primary and secondary slot, but this time no Test or Confirm. Just Upload and Reset.
More about different modes: https://docs.mcuboot.com/design.html#image-slots
A new Mode was added:
NONEto indicate that no Test and no Confirm is sent.If the target supports Bootloader Information command, the mode will be selected automatically even if a different one is selected.
Unfortunately, the nRF Connect Device Manager always asks for the mode after clicking START. This is because the device may not be connected at that point, so the app doesn't know the bootloader mode.
Direct XIP with and without Revert are supported from NCS 2.5 onwards.
