component/bt and esp32: fix two bluetooth bugs that caused by coexist module

1. Fix interrupt watchdog timeout in bluetooth "btdm_bb_isr"
    2. Fix BLE assert(512) or assert(1536)  in rwble.c at line 222
    3. Update librtc.a to fix BLE assert(512) in rwble.c at line 222

    The #1 and #2 occurs random.
    The #3 bug occurs in certain scenario:
    	1. If Wifi start softap and BLE is working
    	2. If wifi start station, but do not use normal station operation, such
    		as just use espnow, while BLE is working
    	3. Any other scenario, that wifi works without use software coexist
    		operation, while BLE is working(such as do advertising and ...)

    4. update libcoexist.a version to v1.1.2
