Restore Ikarus runtime bindings after loading a save

[Solessfir]

Loading a save restores script variables but leaves Ikarus's transient parser and engine bindings uninitialized.

Reproduced with Archolos: dialogue and facial-animation calls work in a new game, then fail after saving and reloading with MEM_GetFuncID: Unresolvable request and an out-of-bounds access to MOB_CREATEITEMS.PAR1.

Call MEM_InitAll after restoring variables and HERO, only for scripts using Ikarus. This does not rerun gameplay initialization, reset NPC routines, or change the save format.

Verified on Windows using the same save and AI_ResetFaceAni call before and after the fix. The call failed before and completed without those errors afterward. Windows and Android ARM64 release builds passed on the development branch before extracting this fix.

Hi, @Solessfir !

Thanks for PR, but I will have to reject it for now. There is no software design on save/load in DMA environment yet. One option is to do same as in regular games: stash whole memory state and transparently restore it on load. Other one - make it dirty to respect Ikarus API to work with archives.

Either way - it's probably too early to start on it, as first priority would be to have DMA work cleanly in use-cases without save/load. Part of it will include: implement reinterpret_cast, develop unit-tests, custom-compiler (for test scripts).
