Windows support

[petethepig]

TODO

• [ ] make pyroscope compile on windows. This shouldn't be too complicated but will take some time for sure as there's a lot of moving parts in the current build process, e.g pyspy, rbspy — I think in v1 we can disable them though. We could also skip this for now and start with macOS and linux
• [x] make exec command work on Windows. I remember this behaving differently between linux and macOS so I imagine we're gonna open a can of worms once we add Windows support https://github.com/pyroscope-io/pyroscope/blob/main/pkg/exec/cli.go#L94

Is anyone working on python support here? I'm receiving this error message:

pyroscope adhoc python mycode.py
Error: spy "pyspy" is not supported. Available spies are: dotnetspy```

Any plans for this issue? :)
