board: st: stm32h7s78-dk: add support for on-board flash

[titouanc]

• st: stm32h7rs: add xspi peripherals
• board: st: stm32h7s78-dk: add support for on-board flash on xspi2

[titouanc]

This currently does not build. It seems that the STM32 HAL for stm32h7rsxx XSPI is incompatible with the Zephyr stm32 xspi flash driver.

For example, with west build -b stm32h7s78_dk zephyr/samples/drivers/flash_shell:
