esp_matter_core: Some changes for device type id.
esp_matter_command: Corresponding changes for renaming of command flags.
esp_matter_ota: Corresponding changes from upstream examples.
zap-generated: Added a common access.h with all the clusters and other corresponding changes in endpoint_config.h.
zap_light: Regenerated zap-generated with the same light.zap file.
strrchr() was being used with a non-null terminated string. This caused the secret key to be outside of the range of the actual data. Fixed it by using a different logic.
Adding constructors to structs for default values of the cluster configs.
esp_matter_command: Removing the support for custom command callbacks and instead using the standard command callback itself. Also some other minor changes to make it easier for the application to use the standard command callback.
