[CPU] Guard InteractionNode usage to x64 only (#34063)
### Details:
- Guard InteractionNode-dependent logic in constructor and
`isSupportedOperation` with `OPENVINO_ARCH_X86_64`
Interaction node source is compiled on non-x64 targets, while
`transformations/cpu_opset/x64/op/interaction.cpp` (which defines
`ov::intel_cpu::InteractionNode`) is excluded by CMake when x64 is OFF.
Issue that is being resolved here: non-x64 links could fail with:
"undefined reference to typeinfo for ov::intel_cpu::InteractionNode"
(e.g. in case of `ov_cpu_unit_tests` on RISCV64).
