* [NPU] subgraph's precision register to kAny

* [NPU] support fill_constant and fill_constant_batch_size_like op bridge and uts

* [NPU] reshape x,y,out node in elementwise ops

[LITE][NPU] Add instance_norm op bridge and unit test, refine the registration of op bridges (#2747)

* [NPU] enhance unittest for shuffle_channel, unsqueeze, pool

test=develop

* Fix the compiling error which occurs when specify the ddk_root path and build for huawei NPU.

* Refine the registration of op bridges and make it similar to the registration of op and kernel.

* Refine the interfaces of the graph and node for op bridges, and support creating constant and data node automatically according to the attribute 'persistable' of the target tensor.

* Add the unit test of the scale and softmax op bridge for NPU.

[LITE][NPU][XPU] Refine subgraph pass, and support NPU/XPU model generation at execution time (#2576)
