Integrate Google Benchmark

## 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

Start by examining how Google Test is integrated into the iceoryx framework, then review the Google Benchmark project and the repository’s existing test organization. Done means Google Benchmark is integrated similarly to Google Test and a separate benchmark folder structure is available for measuring in-process functions and use cases.
