[GHA] [Sanitizers] Transformations func tests show leaks

Details:

• Fix model validation in topological sort when exception throw force unlink nodes to removed dependencies (circular) which allow release nodes without leak.

Pull request overview

Fixes sanitizer-reported leaks triggered when model validation/topological sort detects cycles by explicitly breaking circular dependencies before throwing, and updates several core tests to avoid leaking allocations/nodes when exceptions occur.

Changes:

• Break node argument/control-dependency links on loop detection in topological_sort to allow reference cycles to be released before throwing.
• Add/adjust regression tests that construct cyclic graphs and assert ov::Model creation throws (covering 1-node and 2-node loops, plus a cycle created via output replacement).
• Update a few unit tests to properly own/deallocate allocated resources (allocator aligned allocation; opset create() results).

File	Description
src/core/include/openvino/core/graph_util.hpp	On loop detection, disconnects node inputs/control deps before throwing to prevent leaks from cycles.
src/core/src/descriptor/input.cpp	Simplifies m_src_node assignment when replacing outputs.
src/core/tests/model.cpp	Adds a 2-node cycle regression test for model construction/topological sort throwing.
src/core/tests/node_input_output.cpp	Wraps tests in ov::test namespace and adds a cyclic-model construction throw test to ensure no leaks.
src/core/tests/ov_default_allocator_test.cpp	Ensures aligned allocation test also deallocates the returned pointer.
src/core/tests/conditional_compilation/ov_cc_on.cpp	Wraps OpSet::create*() raw pointers in shared_ptr to avoid test leaks.
src/core/tests/conditional_compilation/ov_cc_off.cpp	Same as above for the “cc off” variant.
