Split the cycle between vfs and profiler.

- Move ProfilerInfo into a subpackage (it's not necessary for profiling, just for analyzing a profile).
- Make some fields in Profiler public for ProfileInfo.
- Mark Profiler as ThreadSafe; there's no cyclic dependency here.

This is based on ulfjack's microbazel patch series: https://github.com/ulfjack/bazel/commit/44553fcac0fc876784d8f48c2e577d8c999712de
