add stubbed-out CHIP v1 clusters from SiLabs

[rwalker-apple]

Problem

CHIP v1 cluster implementations from SiLabs are not incorporated into any builds, although they serve as the baseline for command handling.

Summary of Changes

This PR sets up a framework for pulling these cluster implementations into our favorite sample application

Outstanding (which can be addressed separately):

• pull in updates to endpoint_config.h (and stub out init functions in clusters-callback-stubs.c)
• pull in updates to callback-stub.[ch] (where some callbacks know about cluster plugins)
• pull in updated znet-bookkeeping.[ch] (for reporting)
• pull in new gen_config.h (is normally named <PROJECT>.h)

NOTE to mergers: please retain all commits, as they contain SiLab's contribution provenance.

@bzbarsky-apple @hawk248 ?

[bzbarsky-apple]

Thank you for sorting through this!

[bzbarsky-apple]

We may want to add "Metering" (not "Simple Metering") and "Messaging" to the list, but that can happen in a followup....

[bzbarsky-apple]

This might cause @bhaskar-apple issues with bringing in the color control cluster. If it does, we can comment these out at that point.

@andy31415 @BroderickCarlin @chrisdecenzo One more approval here, please?
