feat: 显存分配器迁移到 VMA（P1 路线第一项）

Browse Source 
- vendored VulkanMemoryAllocator 子模块，唯一实现编译单元 VmaImpl.cpp
- MemoryAllocator 重写为 VMA 后端：接口从"Allocate(reqs)+手绑"升级为
  "创建即分配即绑定"（CreateBuffer/CreateImage/Destroy/Flush），
  VMA 要求资源与内存成对释放，约束成单一出口
- Buffer/Texture/RenderGraph 三处调用方迁移；staging 持久映射 + 按分配
  精确 flush（原来按整块 flush）
- 获得：TLSF 通用分配、DedicatedAllocation 自动启用、memory budget 感知、
  内存别名基础（TAA/复用前置）
- 编译零错误、validation 零警告、8 秒冒烟通过
