1. Remove the bond_device global variable.
2. Fix bond_device add cause memory exception
3. Modify the code location.
4. modify thread security
5. remove esp_ble_clear_bond_device_list() API
6. modify esp_ble_get_gond_device_list() to return list immediately, rather than wait event.
7. modify the gatt_security_server demo to show how to remove all the bonded devices.
8. fix some code bugs may cause something error.
component/bt: cherry-pick the bugfix/btdm_api_manage_pair_info_#13119 to this branch.
component/bt: Change the ble gap API code format & added the status judgment in the btc_storage_load_bonded_ble_devices function.
1. change all gatt cb function to 3 args and function type. add gattc_if/gatts_if as second argument
2. delete gatt_if of "gatt cb param"
3. separate conn_id and gatt_if from conn_id
4. change the demo code as the gatt changed
1. change gap btc args to union to decrease the dram occupied by btc args
2. actually use individual args for every action is the best way(decrease the dram occupy), but for writing code easily and the style, use union
3. gatt server/client should do the same work
