[AGC] Quake rendering progress: WAIT_REG_MEM, draw fixes, VideoOut, and HLE improvements (#68)

* [agc] WAIT_REG_MEM suspend/resume, draw packet fixes, new HLE exports, debug cleanup Rebased onto upstream 79a7437 (par274/sharpemu, rewritten history). - GpuWaitRegistry: DCBs suspended on unsatisfied WAIT_REG_MEM are re-polled against guest memory on every submit; fixed 64-bit and standard packet parse offsets, apply the mask, treat PM4 compare function 0 as "always". - TryReadSubmittedDrawCount: accept the 5-dword ItDrawIndex2 form emitted by DcbDrawIndex (count at +4); menu draws were silently discarded before. - sceAgcDriverSubmitMultiDcbs: reversed ABI (rdi=address array, rsi=dword sizes, rdx=count). - VideoOut: vblank events, sceVideoOutGetFlipStatus, buffers registered via sceVideoOutRegisterBuffers are valid flip targets. - New HLE: libc stdio (fopen/fread/fseek/ftell/fclose/fgets), Dinkumware _Getpctype ctype table, NpTrophy2 stubs, AMPR PAK sequential-read tracker, MsgDialog lifecycle, NGS2 alt NIDs + dummy vtable for handle objects, guarded memset intrinsic, abort()/strcasecmp null-arg recovery. - Removed investigation-only code (INT3 breakpoints, qfont/mcpp dumps, error-candidate printf traces, unconditional debug logs). First rendered frame: Quake (PPSA01880) presents a 1920x1080 guest frame. * Implemented a guarded native intrinsic (rep movsb) in DirectExecutionBackend to bypass HLE dispatch overhead, while preserving memory safety checks.
