feat: reduce GC by not passing the whole struct to compile and process TraceQL metrics

[javiermolinar]

What this PR does:
It aims to marginally reduce allocations by not passing the whole struct to compile and process TraceQL metrics.
It also makes the code simpler to understand by not wrapping the start, end, and step, especially for those methods where the request values were being mutated in unclear ways
