Description
`UseSHA3Intrinsics` was introduced in JDK-8252204, but it was not
auto-enabled due to the lack of real hardware. 

After JDK-8297092, `UseSHA3Intrinsics` is only auto-enabled on hardware with performance benefit. See the code https://github.com/openjdk/jdk/pull/11382/files#diff-a87e260510f34ca7d9b0feb089ad982be8268c5c8aa5a71221f6738b051ea488R338-R345

As a result, test case compiler/intrinsics/sha/cli/TestUseSHA3IntrinsicsOptionOnSupportedCPU.java fails on Neoverse N2 and V1.

ILW = Test fails because requires condition does not work as expected (test bug), single test on Neoverse, no workaround = MLH = P4

This test case compiler/intrinsics/sha/cli/TestUseSHA3IntrinsicsOptionOnSupportedCPU.java was introduced in JDK-8252204. Due to the lack of real hardware, it was not fulled evaluted. I suppose, this case would fail on Neonverse N2/V1 as well then. But it was not exposed since the jtreg test case was only run on simulator. Hence, the "Affects Versions" label is assigned to "17, 18, 19, 20, 21".
