Remove gtest file from cpp library (#9816)
* Fix the apache-rat check
---
**Motivation**
PR #9072 introduces the gtest file but does not exclude for apache-rat
check. So that causes the apache-rat check to fail.
* Move the test to the another file
* Address comments
(cherry picked from commit 0d5f0707f5dc1a80088cad2fdc1f5f3cac63355a)
