Update jit_avx512_core_x8s8s32x_conv_kernel.cpp

[RICKIE777]

Delete 3D depthwise unimplemented judgments

Description

In oneDNN branch v2.4_for_ie_master, the detail commit is https://github.com/openvinotoolkit/oneDNN/commit/10fcf5d4094febe0ad68759fc1718a763023f496 . In src/cpu/x64/jit_avx512_core_x8s8s32x_conv_kernel.cpp file, delete the 3D depthwise unimplemented judgments. BUT these lines are preserved in the latest version v2.7_for_ie_master. If these lines are not deleted, some models on the xeon platform will choose to run with a non-avx512 kernel, resulting in performance degradation. Such as JIRA CVS-98185.
