Lets a Matter switch (opt-in via beginWithBinding()) be bound directly to another device, e.g. a light, and control it without a hub relaying every command - closes SiliconLabsSoftware#101. Adds MatterBindingManager to serve the Binding cluster's list attribute and dispatch bound OnOff commands over CASE/group sessions, built entirely from SDK pieces already available (BindingTable, CASESessionManager, CommandSender) since the official bindings cluster server/BindingManager aren't vendored. Plain begin() and the existing matter_switch/matter_lightbulb examples are untouched; matter_switch_binding and matter_lightbulb_binding demonstrate the new opt-in path.

Re-run uncrustify with package/uncrustify.cfg to match the CI check; whitespace/indentation only, no logic changes.

Summary
Bindingcluster #101 - adds opt-in support for the standard Matter Binding cluster onMatterSwitch(beginWithBinding()), so a switch can be bound directly to another device (e.g. a light) and control it without a hub relaying every command.MatterBindingManager, which serves the Binding cluster's list attribute and dispatches bound OnOff commands over CASE (unicast) or group sessions - built entirely from SDK pieces already available in this repo's vendored SDK/precompiled libs (chip::BindingTable,chip::CASESessionManager,chip::app::CommandSender), since the officialbindingscluster server plugin andBindingManageraren't vendored.begin()and the existingmatter_switch/matter_lightbulbexamples are untouched (verified viaarduino-cli compilethat the plainmatter_switchbinary is unchanged byte-for-byte for its non-binding code paths - only a 136-byte flash delta from the new opt-in method existing).matter_switch_bindingand its companionmatter_lightbulb_binding(a plain lightbulb - no special code needed on that side).Test plan
