Use uint64_t instead of uint32_t for the FLASH_STM32_EX_OP_SECTOR_WP
extended operation.
Some chips have two banks, more than 16 sectors each e.g. stm32h7a3xx
chips, so more than 32 bits are required.

Move the syscall_handler.h header, used internally only to a dedicated
internal folder that should not be used outside of Zephyr.

This patch adds flash readout protection support for STM32F4 devices
family. These devices can enable protection on entire flash content.
Readout protection functionality was exposed as vendor extended
operation. To change readout protection state, caller should provide a
structure which describes desired RDP state.
Enabling readout protection permanently or disabling readout protection
(changing from level 1 to level 0) is guarded by
CONFIG_FLASH_STM32_READOUT_PROTECTION_PERMANENT_ALLOW and
CONFIG_FLASH_STM32_READOUT_PROTECTION_DISABLE_ALLOW respectively.

This patch adds sector write protection support for STM32F4 devices
family. These devices can protect flash content with sector precision.
Write protection functionality was exposed as vendor extended operation.
To change write protection state, caller should provide mask of enabled
and disabled sectors.
Function responsible for locking/unlocking option bytes was implemented
for all STM32 devices supported by this driver.
