controller: Initialize group data provider listener when initializing the controller instance (v1.4.2)
See merge request app-frameworks/esp-matter!1251
All examples already set the C++ standard in the project-level
CMakeLists.txt. The main component redundantly sets it again.
As per the ESP-IDF C++ support guide, a component should only
override the C++ version if it intends to use a different one.
We want to keep a consistent version across the project, so
the redundant setting is removed.
