fix: add explicit type casts for uint64_t operations

Browse Source 
- arm64_check_offset: use (uint64_t)0x1ff for consistency with scaled_mask
- arm64_sub_sp: use 0xffful suffix for uint64_t diff parameter

These changes ensure consistent type handling and avoid implicit
integer promotions when working with 64-bit values.
