[GPU] Fix crash in onednn impl with rank-3 blocked layout (#34190) ### Issue: - When using oneDNN implementation on GPU, the program may terminate with a message `Unexpected layout format`. - The issue is reproducible when layout format is blocked, logical shape rank is 3, and `keep_rank` is not enabled during `layout_to_memory_desc()`. - In this case, the conversion path attempts to map a 4D blocked format to a 3D oneDNN format tag, which is unsupported and triggers an exception. > Traceback (most recent call last): File "C:\Users\helena\code\cica-quantization-failed-exp\Test_Suite\quan-ravi\src\cica_resnetrf_issue.py", line 26, in <module> infer_request.infer() File "C:\Users\helena\venvs\cica_simple_env\lib\site-packages\openvino\_ov_api.py", line 202, in infer return OVDict(super().infer(_data_dispatch( RuntimeError: Exception from src\inference\src\cpp\infer_request.cpp:224: Exception from src\plugins\intel_gpu\src\graph\impls\onednn\utils.cpp:408: [GPU] Unexpected layout format f16:b_fs_yx_fsv16:32x32x4098:nopad ### Root cause: - `MemoryDescriptorBuilder::calculate_dims()` contains a special path for `shape_rank == 3` when `keep_rank == false`. https://github.com/openvinotoolkit/openvino/blob/1869d0becde02ff4b8ab9d378a6861afd9217edd/src/plugins/intel_gpu/src/graph/impls/onednn/utils.cpp#L399-L415 - In that path, the builder tries to convert a 4D clDNN format into a 3D oneDNN format tag. - This conversion relies on `format_map_cldnn_4d_to_onednn_3d`, where blocked formats such as `b_fs_yx_fsv16` are not present in this map. - As a result, the lookup fails and `OPENVINO_THROW("[GPU] Unexpected layout format ...")` is triggered. ### How to fix: - Blocked layouts cannot be safely reduced from 4D to 3D format tags, so that rank must be preserved for such layouts. - Enable `keep_rank` for blocked layouts during oneDNN memory descriptor creation. - This ensures that blocked layouts preserve their original rank, and the invalid 4D→3D format conversion path is skipped. ### Tickets: - CVS-181412
