[FR] Make benchmark tests available from Test Explorer of Visual Studio

**Is your feature request related to a problem? Please describe.**
I noticed that my benchmark tests do not show up in the Test Explorer of Visual Studio. The regular GoogleTest based unit tests do. Is this by design or oversight?

**Describe the solution you'd like**
Is there an option to make the benchmarks available in the Test Explorer via GTA?

**Describe alternatives you've considered**
So far, I only called the RUN_TESTS target of the CMake generated VS solution.

**Additional context**
Analysis of code coverage would then also be possible via VS option "Analyze code coverage by running all tests"
