Add the runtime code versioning feature

This makes tiered compilation work properly with profiler ReJIT, and positions the runtime to integrate other versioning related features together in the future. See the newly added code-versioning design-doc in this commit for more information.

Breaking changes for profilers: See code-versioning-profiler-breaking-changes.md for more details.
