Please add GELU in-place execution support
Created by: jczaja
We recently added in-place execution to oneDNN kernels of softmax, elementwise_add and activations. There is also support in GELU activation, but cannot be used as GELU of PaddlePaddle does not have InplaceInferer e.g. it does not support in-place execution. If possible , please add GELU in-place execution support .
