New version of the old PR #1891

Adding the stm32h7s3l8 nucleo board

Following zephyrproject-rtos/zephyr#76305

Build the application with sysbuild for the nucleo_h7S3L8 :

  1. `west build -p auto -b nucleo_h7s3l8 samples/boards/st/hello_world_xip --sysbuild -- -DSB_CONFIG_BOOTLOADER_MCUBOOT=y -DCONFIG_FLASH_BASE_ADDRESS=0x70000000
  2. then, flash mcuboot at address 0x8000000 and signed hello_world_xip application at 0x70000000 (where i can read the magic nb)

With CONFIG_STM32_MEMMAP flag get NOR flash 32 bytes header
Read the NOR flash to get header of the image.
The FLASH_DEVICE is now the external NOR defined by
the board device tree to be the first qspi/ospi/xspi instance
(not necessarily zephyr, flash-controller)

Define the stm32 disco board configuration to set
the STM32 XIP mode that will enable the MemoryMapped mode.
See Kconfig of the stm32 soc. Choose the mcu_boot partition
where to build ../bootloader/mcuboot/boot/zephyr

requires the zephyrproject-rtos/zephyr#82275 which introduces the nucleo_h7s3l8 target
The application running in the external flash is a samples/hello_world available in the branch https://github.com/FRASTM/zephyr/tree/xip_h7s3
