[byungilm]

• when dependency is fc and is_type_conversion_only is true

Description of the issue

• From analysis of Qwen-Reranker (CVS-173218), Reorder 'Result_33640' should be optimized.

The code and line that caused this issue

• Added FC to condifion for fusing reorder : remove_redundant_reorders.cpp, layout_optimizer.cpp
• Added condition to remove reorder : reorder_inst.h

Reproduction step and snapshot

• target model QWen3-Reranker-0.6B is in openvino_notebook (notebooks/Qwen3-embedding)
• Reproduced by benchmark_app
  ./benchmark_app -m openvino_notebooks/notebooks/qwen3-embedding/Qwen3-Reranker-0.6B/FP16/openvino_model.xml -shape [16,256] -d GPU -hint latency -api sync -nireq 1 -niter 10
