This adds a OPENMP_TEST_ENABLE_TSAN option that allows to override whether tests using tsan will be enabled. The option defaults to the existing auto-detection. The background here is https://github.com/llvm/llvm-project/issues/111492, where we have some systems where tsan doesn't work, but we do still want to build it and run tests that don't use tsan.
