MemoryManager::CreatePoolAllocator
std::unique_ptr<PoolAllocator> CreatePoolAllocator(size_t blockSize, size_t count);
创建并返回一个新的 PoolAllocator 实例，使用系统分配器作为底层。返回的 unique_ptr 管理分配器生命周期。
参数：
blockSize- 每个内存块的大小（字节）count- 内存池中块的数量
返回： PoolAllocator 的 unique_ptr
复杂度： O(blockSize * count)（需要预分配所有块）
示例：
#include <XCEngine/Memory/MemoryManager.h>
struct Particle {
float x, y, z;
float life;
};
auto pool = MemoryManager::Get().CreatePoolAllocator(sizeof(Particle), 1000);
void* block = pool->Allocate();
auto* p = new (block) Particle{1.0f, 2.0f, 3.0f, 5.0f};
p->~Particle();
pool->Free(block);
