[CMake] Create a real library instead of an object library for stress tests Object libraries don't allow linking to other libraries, which makes it impossible to link it to libcds, on which it depends. It used to work because all flags were set globally, so the object library picked them up as well.
Added SPSC queue stress tests
Split stress-queue test
[CI] Changed CMake scripts for tests
Migrated queue stress test to gtest framework
