Split CHIPClusters.cpp to speed up compilation. (#11091)

* Split CHIPClusters.cpp This splits up CHIPClusters.cpp into a couple of different files: - CHIPClusters.cpp contains no template specialized methods. - CHIPClustersInvoke.cpp contains all template specialized methods for invoking commands. - CHIPClustersWrite.cpp contains all template specialized methods for doing writes. This resulted in a speed-up of about 30s (from 1m50s to 1m20s) when doing an incremental compilation of chip-tool after touching CHIPClusters.cpp. It does this by better leveraging -jX builds to parallelize compilation. More importantly, this might also provide a pattern for others (like Android) that is running into OOM issues with clang compiling CHIPClusters.cpp. * Apply suggestions from code review Co-authored-by: Boris Zbarsky <bzbarsky@apple.com> * Fix regen breakaga * Address review feedback Co-authored-by: Justin Wood <woody@apple.com> Co-authored-by: Boris Zbarsky <bzbarsky@apple.com>
