Code Savings Guide for Matter Applications

• Remove unnecessary clusters from the zap configuration. Example applications have clusters enabled to support both Thread and WiFi transport layers such as the Diagnostics clusters.

• Remove optional features in Matter that may not be needed for a certain application. In the EFR32 build script, there are additional build arguments that are added to either add or remove optional Matter features. For example, added a build argument disable_lcd=true will save flash by disabling the lcd screen. For inspiration, a minimalistic lighting application is provided. This example showcases the minimal requirements to build a lighting application over the Thread protocol.
