PTA APIs in BLE_Stack library: Two APIs are designed in BLE_Stack library.
BT_SYS_PtaInit: It is called within APP_PtaInit() to enable BLE stack PTA
feature.
BT_SYS_PtaWlanActiveIrqHandler: It is called within
APP_PtaWlanActiveIrqHandler() to handle WLAN_ACTIVE signal.
MCC configuration: Below MCC configurations will apply when BLE MCC component
PTA option is enabled.
Modify GPIO MCC configuration to fit PTA pin definition.
Including app_pta_handler.c and app_pta_handler.h to project.
Generate application template code to call APP_PtaInit() in
APP_BleStackInitAdvance().
BT Request priority design: Except for the BT device is scanning for
advertising packets or RSSI measurements for channel classification, others BT
activities are high priority.
