Improve CI

[korniltsev]

currently we suffer from couple of things

• arm runners
• macos runners
• a lot of build logic is located in gh actions yamls

We could improve

• [x] - ~use grafana drone ci to leverage its runners~
  • [ ] ~drone is not running on main branch, only PR~
  • [ ] Do not use drone CI
• [x] - run everything in docker, do not rely on runner python/ruby version
• [x] when running manylinux.sh - create a docker image from scratch instead of mounting a dir with docker run
• [x] - use cargo workspaces
• [x] - create makefiles/scripts to do the build so that build logic is in the makefiles and not in yaml
• [ ] - automatically bump version https://github.com/grafana/pyroscope-rs/actions/runs/5343723738
• [x] - publish rbspy fork to crates
• [ ] - publish cli to crates
• [x] - subprojects seem to not share build cache for some reason - if I build ffi/python and ffi/ruby, libraries seem to be built from scratch, not sure why
• [ ] run tests on all architectures (arm64,amd64), platforms (linux, mac)

Also, we should make sure that versions are not changing on their own: https://github.com/grafana/pyroscope-rs/pull/134#issuecomment-1711160180

I've updated the build image for now, but this is not a solution

Another issue is that we're currently using pyroscope.cloud in tests: https://github.com/grafana/pyroscope-rs/issues/154
