Add more profiling tools

[piohei]

This PR adds integration with tracy tools as well as information about using other profiling tools.

For e2e-testing to pass I needed to introduce new binary name with -profiled suffix. Now tests are running without profiling enabled by default.

CodSpeed WallTime Performance Report

Merging #134 will not alter performance

_{Comparing piohei/profiling (1a0c336) with main (b0f12f9)}

⚠️ Unknown Walltime execution environment detected

Using the Walltime instrument on standard Hosted Runners will lead to inconsistent data.

For the most accurate results, we recommend using CodSpeed Macro Runners: bare-metal machines fine-tuned for performance measurement consistency.
