kselftest/arm64: Add HWCAP test for FEAT_LS64
Add tests for FEAT_LS64. Issue related instructions if feature
presents, no SIGILL should be received. When such instructions
operate on Device memory or non-cacheable memory, we may received
a SIGBUS during the test (w/o FEAT_LS64WB). Just ignore it since
we only tested whether the instruction itself can be issued as
expected on platforms declaring the support of such features.
