RFR: 8266401: mark hotspot compiler/intrinsics/sha/cli tests which ignore VM flags

[Jie Fu]

Hi all,

Could you please review this small and trivial patch that adds `@requires vm.flagless` to `compiler/intrinsics/sha/cli ` tests that ignore VM flags?

This change makes sense since it will fix some test failures when testing with extra VM flags.

For example, the following three failures will be fixed when testing with UseAVX<2 on Intel CPUs.

compiler/intrinsics/sha/cli/TestUseSHA256IntrinsicsOptionOnUnsupportedCPU.java
compiler/intrinsics/sha/cli/TestUseSHAOptionOnUnsupportedCPU.java
compiler/intrinsics/sha/cli/TestUseSHA512IntrinsicsOptionOnUnsupportedCPU.java


Thanks.
Best regards,
Jie
