Update bt lib for ESP32

- Add config to set duplicate scan list refresh period
- overwrite the oldest device infor if the list is full
- Fixed duplicate scan period is not accurate
- Change default TX power to 9 dBm
- Fixed disconnect reason 0x1f (unspecified error)
- Fixed connection timeout due to terminate ind has not been acknowledged
- Fixed some memory was not released after bluetooth controller initialization failed on ESP32

+                If the period value is non-zero, the controller will periodically clear the device information
+                stored in the scan duuplicate filter. If it is 0, the scan duuplicate filter will not be cleared
+                until the scanning is disabled. Duplicate advertisements for this period should not be sent to the
+                Host in advertising report events.
+                There are two scenarios where the ADV packet will be repeatedly reported:
+                1. The duplicate scan cache is full, the controller will delete the oldest device information and
+                add new device information.
+                2. When the refresh period is up, the controller will clear all device information and start filtering
+                again.
