ssdfasd f427699ac6 refactor: improve test infrastructure and fix OpenGL GLAD initialization
- Rename D3D12Enum.h to D3D12Enums.h for naming consistency
- Fix OpenGL unit test GLAD initialization by using gladLoadGL()
  instead of gladLoadGLLoader(wglGetProcAddress) for fallback support
- Migrate remaining tests to use gtest_discover_tests for granular
  test discovery (math, core, containers, memory, threading, debug,
  components, scene, resources, input, opengl)
- Remove obsolete TEST_RESOURCES_DIR and copy_directory commands
  from OpenGL unit test CMakeLists (minimal/Res doesn't exist)
- Update TEST_SPEC.md with performance metrics and per-module
  build/test commands for faster development workflow
- Update CMake path references to use lowercase paths

# ReadWriteLock::WriteLock
```cpp
void WriteLock()
```
获取写锁(独占)。如果有读者持有锁或有其他写者正在等待,当前线程将阻塞,直到获得独占访问权。
**参数:**
**返回:**
**线程安全:**
**复杂度:** 平均 O(1),写者饥饿时可能 O(n)
**注意:**
- 写锁为独占访问,持有期间不允许任何读锁或写锁。
- 写锁具有优先权,会阻塞后续到达的读者。
- 同一线程不可重复 WriteLock。
**示例:**
```cpp
#include "XCEngine/Threading/ReadWriteLock.h"
#include <vector>
XCEngine::Threading::ReadWriteLock rwLock;
std::vector<int> buffer;
void Append(int value) {
rwLock.WriteLock();
buffer.push_back(value);
rwLock.WriteUnlock();
}
```
