Describe
Add Gpu context.
TODO：
1、现有的GPU Allocator需要stream参数，因此GPUContext的初始化需要拆分为【不需要allocator资源的初始化】和【需要allocator资源（eigen_device，cudnn_workspace）的初始化】；（该行为与设计不一致，需在GPU Allocator修改后同步修改）
2、
SetDeviceAllocator接口名更改为SetAllocator；3、Pten下DeviceContext默认构造为空构造，（设置Allocator资源后）调用
Init()函数初始化资源，预测调用SetXxx函数使用；4、StreamCallback功能去除thread_pool头文件，使用std::async替代。
