Enable backtrace in unit tests (#17655)

### Description
Google test can be built either with absl/re2 or not. This PR enables
the build option so that google test framework can print out a nice
stacktrace when something went wrong. It helps locate test errors in CI
build pipelines.

Also, Google test will remove the build option and make it always ON. So
sooner or later we must make this change.
