MemoryManager::CreateLinearAllocator
std::unique_ptr<LinearAllocator> CreateLinearAllocator(size_t size);
创建并返回一个新的 LinearAllocator 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：
size- 分配器缓冲区大小（字节）
返回： LinearAllocator 的 unique_ptr
复杂度： O(1)
示例：
#include <XCEngine/Memory/MemoryManager.h>
auto linear = MemoryManager::Get().CreateLinearAllocator(1024 * 1024);
void* ptr = linear->Allocate(256);
void* marker = linear->GetMarker();
linear->Allocate(128);
linear->SetMarker(marker);
linear->Clear();
