Refactors the core guest memory access subsystem (guest.h) to be safer and portable accross host systems with different endianness. The previous implementation used direct pointer casting, which is not endian safe. 1. All read and write functions have been converted from unsafe pointer casts to memcpy(). This resolves alignment warning -Wcast-align. 2. The access functions no longer rely on asserts for error checking. They now perform explicit boundary and alignment checking and returns a guest_mem_access_result_t status code. 3. A new header (endian.h) provides cross platform byte swapping macros. The memory access functions use these macros to ensure that the guest always sees memory in the correct endian format, regardless of the host's native byte order. The host endianness is now automatically detected via CMake. 3. Asserts are now explicitly enabled in release builds to catch critical errors. Signed-off-by: Ronald Caesar <github43132@proton.me>
