NCSDK-33237: Extend firmware loader companion application for nRF54H20

[tomchy]

This PR extends an existing firmware loader application, so it is possible to include it in projects built for nRF54H20.

It also enables building the single_slot sample on nrf54h20.

Testing:

$ west build -p -b nrf54h20dk/nrf54h20/cpuapp samples/dfu/single_slot

Pull Request Overview

This PR adds firmware loader support for the nRF54H20 platform to the single_slot DFU sample. The implementation uses a merged slot configuration where MCUboot can boot either the main application or a lightweight firmware loader that enables over-the-air updates via Bluetooth.

Key Changes:

• Implements merged partition layout for nRF54H20 supporting both main application and firmware loader modes
• Adds optimized BLE MCUmgr-based firmware loader with minimal footprint
• Configures MCUboot to support button-triggered firmware loader activation

This sample is not intended for standalone building. As stated inside the README.rst file:

any sample under sample should be possible to build stand-alone in order for users to have a starting point with a sane configuration from where they can include the sample into their own product.

Besides that, the same warnings are printed with twister, so please fix:

$ west twister -T samples/dfu/fw_loader/ble_mcumgr/

I like the direction 👍

Please take a look at the remote board handling, we try to get a cleaner and more overall consistent approach where downstream users can more easily create their own board based on Nordic's SoCs.
