Prototyping and testing nuget build reconstruction

[JanKrivanek]

Idea by @baronfel

Motivation

#8398 needs experimentation with nuget build reconstruction options - and evaluating those on top N nugets (https://www.nuget.org/stats, let's shoot for top 100)

Expected outputs

• [not production level quality] harness for running through top N nuget packages, run the injected build reconstruction code and evaluating results
• Stats and suggestion based on results for 2 main build reconstruction techniques:
  • Nuget build reconstruction - Compiler flags #8511
  • Nuget build reconstruction - Repo root build #8512

Results summarization: OneNote [internal]

Very summarized, out of context peek on data:
