Integrate Google Benchmark

[MatthiasKillat]

Brief feature description

Integrate https://github.com/google/benchmark into iceoryx framework to admit microbenchmarks.

• can be used similar to tests to measure runtime of specific functions or specific use cases
• not useful for benchmarks across processes (e.g. publish-receive cycles)
• can also measure the time of various integration test-like setups in the same process
• useful during development to compare specific implementations

Detailed information

• integration should be similar to Google Test
• we can then create a separate folder structure (e.g. parallel to tests) for various benchmarks

@dkroenke @elBoberido What do you think? Not for 2.0 of course and low prio.

[elBoberido]

@MatthiasKillat great idea and yes, I think there are some topics with a higher priority for 2.0 but a nice side topic

Oh this would be awesome. When we would have a dedicated CI target like a raspberry pi somewhere we could also signal a warning in the CI when certain performances have degraded.
