1. When there is a large shambridge memory which is not
deleted in time, The shambridge in QTEE might be out of
memory. we met this issue in the TVM TUI unit test.
TrustedUISampleTest -vm --gtest_filter=*Basic_TUIStartStop*
2. To avoid being out of shambridge memory, we should postpone
the deletion of shambridge created by smcinvoke itself.

1.When the QTEE is busy with a high concurrency, the objects and shared
memory bridge will not be released and deleted in time, this will lead
to memory leakage issues in the QTEE.
2.To avoid the memory leakage in case of EBUSY, we add 2 exclusive worker
threads to postprocess the object release and shmbridge deletion
separately.

Acquire lock before delete_cb_txn_locked.

release the lock afterwards.
Also rename the api with_locked to state that api
needs to be called on locked mutex.
