Shared Memory Concurrent Map (#16704)

Adds a fast, scalable, fine-grained concurrent map to the package
modules. Its API attempts to match the Map standard module, and
may be suitable as a replacement implementation or as reference
material for future efforts.

This effort has been long in the undertaking. A very special thanks
to @dgarvit for continuing to work on this PR and prepare it for
merging.

Thanks to @dgarvit, @LouisJenkinsCS!

  • Get ConcurrentMap to work with owned and shared
