samples: zephyr: smp_svr_mini_boot: Add 'swap using move' config

This commit adds a new sample configuration for the SMP server
mini boot sample that uses the swap using move mode of MCUboot.
This configuration is useful for testing and demonstrating the
functionality of the swap using move feature in a minimal setup.

Documentation has been updated with instructions on how to build
the sample with direct-xip mode or swap using move mode.

 This sample shows how to configure MCUboot for secure boot and Device Firmware Update (DFU) capabilities using the Zephyr RTOS.
 The MCUboot is configured to utilize hardware cryptography with the :ref:`ED25519 signature <ug_nrf54l_cryptography>`. Additionally, for nRF54L15 DK  :ref:`Key Management Unit (KMU) <ug_nrf54l_developing_basics_kmu>` for secure key storage is used.
-The setup uses LTO, direct-xip mode and disables non-essential functionalities to downsize the MCUboot non-volatile memory footprint.
+The setup uses LTO and disables non-essential functionalities to downsize the MCUboot non-volatile memory footprint.
 
 The SMP server sample is configured to support Bluetooth® LE and shell for the MCUmgr protocol, which facilitates image management and OS commands.
 
+To achieve minimal size, direct-xip mode can be used, though you can build the sample with the swap using move mode as well.

 For nRF54L15 DK, make sure you are building your project with the ``SB_CONFIG_MCUBOOT_GENERATE_DEFAULT_KMU_KEYFILE`` Kconfig option enabled.
 
+For direct-xip mode, you must build the sample with the ``SB_CONFIG_MCUBOOT_MODE_DIRECT_XIP`` Kconfig option enabled.
+For swap using move mode, use the ``SB_CONFIG_MCUBOOT_MODE_SWAP_USING_MOVE`` Kconfig option instead.
+
 You will notice that the size of MCUboot is significantly reduced in comparison to the default configuration.
 
 If you are using command line, you must run the ``west flash --erase`` command to enable KMU provisioning.
