GRUCell fusion transformation (#12843)

* GRUCell fusion transformation and tests

* Enable GRUCell fusion transformation in MOC

* add missed include

* add missed include again

* fix warning in the tests

* Apply review comments

* Use NodeRegistry in GRUCellFusion transformation, apply review comments

* Add support for both formats zrh and rzh

* move additional checks to pattern, remove the transformation from MOC

* fix conflict with master branch

* apply review comments

* Update src/tests/functional/inference_engine/transformations/common_optimizations/gru_cell_fusion.cpp
