Add DirectX 8 Support - Complete DX8/DX9/DX12 Abstraction

Browse Source 
NOW SUPPORTING ALL THREE APIs: DX8, DX9, DX12!

✅ Added DirectX 8 Support:

1. GraphicsDeviceDX8.h/cpp
   - Full DX8 implementation
   - Direct3D8 device management
   - Compatible with legacy DX8 code

2. Updated Factory (Auto-Detection)
   - Priority: DX12 > DX9 > DX8
   - Automatic fallback
   - Manual API selection

3. Updated GraphicsManager
   - GetD3D8Device()
   - GetD3D9Device()
   - IsUsingDX8/DX9/DX12()

🎯 USAGE:

// Auto (DX12 > DX9 > DX8)
g_Graphics.Initialize(hwnd, 1280, 720);

// Force DX8
g_Graphics.Initialize(hwnd, 1280, 720, true, GraphicsAPI::DirectX8);

// Force DX9
g_Graphics.Initialize(hwnd, 1280, 720, true, GraphicsAPI::DirectX9);

// Force DX12
g_Graphics.Initialize(hwnd, 1280, 720, true, GraphicsAPI::DirectX12);

// Command line
Game.exe -dx8    # DirectX 8
Game.exe -dx9    # DirectX 9
Game.exe -dx12   # DirectX 12

✨ COMPLETE ABSTRACTION:
Same code works across ALL three APIs!

# Graphics Abstraction Layer
## 개요
DX8/DX9/DX12를 런타임에 전환할 수 있는 통합 그래픽 인터페이스
**DX8/DX9/DX12를 런타임에 전환**할 수 있는 통합 그래픽 인터페이스
## 지원 API
- ✅ DirectX 8
- ✅ DirectX 9
- ✅ DirectX 12
## 사용법
### 기본 초기화
### 초기화
```cpp
#include "Graphics/GraphicsManager.h"
// 자동 선택 (DX12 지원하면 DX12, 아니면 DX9)
// 자동 선택 (DX12 > DX9 > DX8)
g_Graphics.Initialize(hwnd, 1280, 720);
// 또는 명시적으로 선택
// 명시적 선택
g_Graphics.Initialize(hwnd, 1280, 720, true, GraphicsAPI::DirectX8);
g_Graphics.Initialize(hwnd, 1280, 720, true, GraphicsAPI::DirectX9);
g_Graphics.Initialize(hwnd, 1280, 720, true, GraphicsAPI::DirectX12);
```
### 렌더링 루프
### 렌더링
```cpp
while (running)
{
g_Graphics.BeginFrame();
g_Graphics.Clear(0xFF0000FF); // Blue
// 렌더링 명령...
g_Graphics.Clear(0xFF0000FF);
// 렌더링...
g_Graphics.EndFrame();
g_Graphics.Present();
}
```
### 레거시 코드 호환성
### API별 디바이스 접근
```cpp
// DX9 전용 코드가 있다면
if (!g_Graphics.IsUsingDX12())
{
LPDIRECT3DDEVICE9 device = g_Graphics.GetD3D9Device();
device->SetRenderState(...);
}
// DX8
if (g_Graphics.IsUsingDX8())
LPDIRECT3DDEVICE8 dev = g_Graphics.GetD3D8Device();
// DX9
if (g_Graphics.IsUsingDX9())
LPDIRECT3DDEVICE9 dev = g_Graphics.GetD3D9Device();
// DX12
if (g_Graphics.IsUsingDX12())
ID3D12Device* dev = (ID3D12Device*)g_Graphics.GetNativeDevice();
```
### API 확인
```cpp
if (g_Graphics.IsUsingDX12())
printf("Using %s\n", g_Graphics.GetAPIName());
### 실행 시 선택
```bash
Game.exe # 자동 (DX12 > DX9 > DX8)
Game.exe -dx8 # DirectX 8 강제
Game.exe -dx9 # DirectX 9 강제
Game.exe -dx12 # DirectX 12 강제
```
## 파일 구조
- `IGraphicsDevice.h` - 추상 인터페이스
- `GraphicsDeviceDX8.h/cpp` - DX8 구현 ⭐ NEW
- `GraphicsDeviceDX9.h/cpp` - DX9 구현
- `GraphicsDeviceDX12.h/cpp` - DX12 구현
- `GraphicsDeviceFactory.cpp` - 팩토리
- `GraphicsDeviceDX12.h/cpp` - DX12 구현
- `GraphicsDeviceFactory.cpp` - 팩토리 (자동 선택)
- `GraphicsManager.h/cpp` - 싱글톤 관리자
## 통합 방법
### BaseGraphicsLayer 수정
```cpp
// 기존
BaseGraphicsLayer::Create(...);
BaseGraphicsLayer::GetDevice();
// 새로운
g_Graphics.Initialize(...);
g_Graphics.GetD3D9Device(); // DX9 호환
```
완전히 투명하게 작동합니다!
## 완전 투명!
모든 API에서 **동일한 코드**가 작동합니다!
