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.
- Driver specific changes for updated button component in examples.
- Updated the device_hal code for button component upgrade.
- Updated the idf_component.yml of examples to use latest version of espressif/cmake_utilities.
primitive data type
Removed config option ESP_MATTER_NVS_USE_COMPACT_ATTR_STORAGE.
Previously, the ESP_MATTER_NVS_USE_COMPACT_ATTR_STORAGE option
determined whether to store attributes as a blob or a primitive data
type in NVS. Since this configuration is not backward compatible, we now
read the attribute as a primitive data type if not found. If it's a
blob, we read it and rewrite it as a primitive data type.
