[EC-770] Implement MessagePack on Watch sync (#2264)

* EC-770 Started implementing MessagePack for the iPhone -> Watch communication

* EC-770 Removed Pods and installed MessagePack through SPM

* EC-770 Implemented MessagePack + Lzfse compression when syncing iPhone -> Watch

* EC-770 Added MessagePack as submodule and updated the build to checkout the submodule as well. Also added MessagePack files as reference in the watch project

* EC-770 Updated build

Updated build.yml to checkout submodules on iOS
