github: workflows: Enable graph builds for aarch64 CI

[theComputeKid]

Enabling graph builds in the CI so we can monitor breakages for aarch64. To do this, I had to deal with solving some aarch64 compiler warnings, same as those that appeared in #2118. So I adopted the same resolution as suggested for that PR.

For MacOS we only test graph for release mode with clang as the smoke tests take too long in debug mode (1 hour+).

Fixes #2137.

LGTM.

@mgouicem I did need to touch a graph file, but I think you might be able to also approve considering the trivial change (we have also done this change before in the PR I linked), in case we don't get a review from the graph team.

It seems this is making macOS CI fail.

The following tests FAILED:
	160 - test_graph_unit_dnnl_mqa_decomp_usm_cpu (SEGFAULT)

This test should not be running though (usm CPU should be a thing only for SYCL CPU configuration, which is not a thing at all on macOS [and maybe even ARM?]).

@mgouicem , it's the bad naming for the test. Even it's not SYCL runtime, "usm" is appended into the test name. The is an internal PR fixing the test names. @ElaineBao is working on that.

@TaoLv whatever the new name is, do we need to add it to the test exclusions list for MacOS? But I am surprised how this happened, because the CI for this PR passed.

[TaoLv]

Yes. I see you already added SKIPPED_TEST_FAILURES+="|test_graph_unit_dnnl_sdp_decomp_usm_cpu" in this PR. I feel test_graph_unit_dnnl_mqa_decomp_usm_cpu should be handled in the same way.
