[compiler-rt] [sanitizer-common] sanitizer_array_ref_test should not require C++17 (PR #161252)

[Andrew Haberlandt via llvm-commits]

https://github.com/ndrewh created https://github.com/llvm/llvm-project/pull/161252

Currently, sanitizer_array_ref_test requires -std=c++17 or newer, due to is_trivially_copyable_v. This is the only test that requires c++17, and thus we use the c++14-available std::is_trivially_copyable instead for now, rather than adding the c++17 cflag.
