Based on #97037

Similarly to what is done for stm32h750_dk board in #97037, introduce a ext_flash_app board variant aiming at being chainloaded by MCUBoot.
Requires mcuboot counter part (mcu-tools/mcuboot#2510) to allow MCUBoot to run on internal flash.

Doc not provided, waiting for #97037 to be merged.
@JarmouniA, in a fisrst step, I plan to redirect doc to stm32h750_dk to avoid redundant doc in each board.

Add ext_flash_app variant to stm32h7s78_dk to allow building
application running on ext flash.

Largely based on A.Jarmouni's work to enable the same on stm32h750_dk
in PR 97037.

Now that ext_flash_app variant is available, it should be used for
mcuboot related apps on this board.
