LOG: [clang] Disable avx512vlcd test on Arm 32-bit

When clang is compiled with a more recent clang
(that includes 5d7f324614d7a5c0de89cfe8295a9b2b7ef5d073),
the code produced enforces 64-bit alignment on a type
that is used during this test.

For reasons not known yet, that type is not 64-bit aligned
though you would normally expect it to be.

See https://github.com/llvm/llvm-project/issues/172994.

I would xfail this but I'm not 100% sure that it always fails.
Memory layout may make it pass sometimes.
