add cinn_launch_op for using CINN to optimize graph (#36600)

增加CinnLaunchOp，负责执行Cinn子图编译的结果，要点如下：
1. 在子图划分的BuildCinnPass中，每个子图在原图中会被替换为该CinnLaunchOp，由它来调用Cinn进行子图编译、执行的功能。
2. CinnLaunchOp的输入/输出即为子图的输入和输出，另外增加`compilation_key`属性，它可由该属性key从全局Cache中获取子图对象、编译结果，该属性由BuildCinnPass在创建Op时进行设置
3. CinnLaunchOp功能实现的流程为：
        - 从全局Cache中获取子图对象
        - 从全局Cache中获取子图编译结果，未命中cache时进行即时编译
        - 根据编译结果的变量信息(数据类型、shape）初始化运行时数据，分配内存/显存
        - 将运行时数据打包为参数，调用cinn的可执行对象runtime program进行计算
        - 子图运行结果通过参数指针同步到paddle侧的tensor

+CinnLaunch Operator.
+
+This operator is used to launch CINN(https://github.com/PaddlePaddle/CINN/blob/develop/README.md)
+to compile a graph and execute the compiled object.
+
+Both input and output of this operator are a set of variables
+which are input and output of the graph respectively that will be
+compiled and executed in this operator.
+In addition, there is an attribute named 'compilation_key' should be
+set necessarily to get corresponding ir::Graph object of the graph
+or its computation result.
+
+It accomplishs the computation of graph following several steps:
+  1. Fetch ir::Graph object from CinnCompiler using kCompilationKey
+  2. Compile the graph to a compiled object, and insert it to the
+     global cache so that we can directly query it from this cache next time
+     when shape of input variables are not changed at all.
+  3. Create and instantiate all variables used to execute compiled runtime program
+     if necessary according to the info(type,shape) included in the return scope.
+  4. Pack each tensor buffer of all above variables as execution arguments.
+  5. Launch execution of the runtime program with above arguments, then
+     the result would be output by writing value on underlying buffer address.
