1: replace api esp_hf_ag_devices_status_indchange with esp_hf_ag_ciev_report in bluetooth
hfp_ag example to send device status of AG to HF unit.
2: remove the unused codes
Due to the lack of synchronized connections, the hf_client can not create audio_connection to
hf_ag. Set default number of synchronized connection to 1.

This updates the minimal supported version of CMake to 3.16, which in turn enables us to use more CMake features and have a cleaner build system.
This is the version that provides most new features and also the one we use in our latest docker image for CI.
This commit removes the usage of all legacy FreeRTOS data types that
are exposed via configENABLE_BACKWARD_COMPATIBILITY. Legacy types can
still be used by enabling CONFIG_FREERTOS_ENABLE_BACKWARD_COMPATIBILITY.
