Start supporting node in exec-harness

[GuillaumeLagrange]

Current limitations:

1. Walltime benchmarking works, but the profiling is unreliable until we tackle things properly for the whole of walltime nodejs profiling.
2. Simulation works with the caveat that we do not support subprocesses (yet) -> tools like tsx etc to run typescript are limited.
3. For both modes, we do not transform symbols from node because post processing is quite destructive, and will keep symbols like JS:^busywait file:///home/guillaume/codspeed/codspeed-integrations-e2e-tests/nodejs/main.js:6:18 in the profile data until we can explicitly set the language for post processing as a user config
