Byte Alignment to support STM32U5

[macharlachanakya]

• Modified #if BOOT_MAX_ALIGN == 8 to #if (BOOT_MAX_ALIGN == 8) || (BOOT_MAX_ALIGN == 16) for boot_img_magic in boot/bootutil/src/bootutil_public.c, because STM32U5 supports 16 Byte alignment.

• Provided #if !defined( BOOT_MAX_ALIGN ) preprocessor directive for #define BOOT_MAX_ALIGN 8 in boot/bootutil/include/bootutil/bootutil_public.h, because STM32U5 supports 16 Byte alignment which can be provided with preprocessor options as #define BOOT_MAX_ALIGN 16.
