mcuboot: Kconfig options allowing to inform on MCUboot config

Browse source 
The commit adds Kconfig options that allow to inform application
what algorithm is used with MCUboot that will be booting
applications on board.
Kconfig options added:
 - CONFIG_MCUBOOT_BOOTLOADER_MODE_SWAP_WITHOUT_SCRATCH
 - CONFIG_MCUBOOT_BOOTLOADER_MODE_SWAP_SCRATCH
 - CONFIG_MCUBOOT_BOOTLOADER_MODE_SINGLE_APP
 - CONFIG_MCUBOOT_BOOTLOADER_MODE_DIRECT_XIP

choice MCUBOOT_BOOTLOADER_MODE
prompt "Application assumed MCUboot mode of operation"
default MCUBOOT_BOOTLOADER_MODE_SWAP_WITHOUT_SCRATCH # MCUBOOT_BOOTLOADER_MODE
help
Informs application build on assumed MCUboot mode of operation.
This is important for validataing application against DT configuration,
which is done by west sign.
config MCUBOOT_BOOTLOADER_MODE_SINGLE_APP
bool "MCUboot has been configured for single slot execution"
help
MCUboot will only boot slot0_partition placed application and does
not care about other slots. In this mode application is not able
to DFU its own update to secondary slot and all updates need to
be performed using MCUboot serial recovery.
config MCUBOOT_BOOTLOADER_MODE_SWAP_WITHOUT_SCRATCH
bool "MCUboot has been configured for swap without scratch operation"
help
MCUboot expects slot0_partition and slot1_partition to be present
in DT and application will boot from slot0_partition.
config MCUBOOT_BOOTLOADER_MODE_SWAP_SCRATCH
bool "MCUboot has been configured for swap using scratch operation"
help
MCUboot expects slot0_partition, slot1_partition and scratch_partition
to be present in DT, and application will boot from slot0_partition.
In this mode scratch_partition is used as temporary storage when
MCUboot swaps application from the secondary slot to the primary
slot.
config MCUBOOT_BOOTLOADER_MODE_DIRECT_XIP
bool "MCUboot has been configured for DirectXIP operation"
help
MCUboot expects slot0_partition and slot1_partition to exist in DT.
In this mode MCUboot can boot from either partition and will
select one with higher application image version, which usually
means major.minor.patch triple, unless BOOT_VERSION_CMP_USE_BUILD_NUMBER
is also selected that enables comparison of build number.
