[nrf noup] kconfig: reduce downstream patch

squash! [nrf noup] treewide: add NCS partition manager support

Source the file 'Kconfig.mcuboot' from sdk-nrf to reduce the amount
of downstream patches in boot/zephyr/Kconfig.

NOTE TO UPMERGE AUTHOR:
This commit removes all but one downstream patches to the file
boot/zephyr/Kconfig. The only remaining patch should be the
sourcing of the Kconfig file in the mcuboot module in the nrf repo.

Hence there should be no modification to this file by any of the
[nrf noup] commits (except one)

noup commits with modifications that should be discarded:
[nrf noup] treewide: add NCS partition manager support
        4eba780
        ! With the exception of the one line added by squashing this
        ! commit.
