…ass `shared_ptr` to bind parameter UBOs" ## Context In keeping with the below changeset in this stack, this diff introduces the `ParamsBindList` structure to avoid storing shared pointers to `api::UniformParamsBuffer` objects in `ExecuteNode` and `PrepackNode`. The idea is to store the binding information of each UPB instead of taking ownership of the UPB itself. There isn't really a need for `ExecuteNode` and `PrepackNode` to take ownership since `ComputeGraph` provides a guarantee that the UPBs will be in scope at the time of binding. With this change, all `shared_ptr` members can be eliminated from `vTensor`, further reducing heap allocations and pointer chasing. In the future I will change `prepack_nodes_` and `execute_nodes_` to store `PrepackNode` and `ExecuteNode` instances directly instead of storing unique pointers to them.
