tpm-backend: Move thread handling inside TPMBackend
Move thread handling inside TPMBackend, this way backend implementations need
not to maintain their own thread life cycle, instead they needs to implement
'handle_request()' class method that always been called from a thread.
This change made tpm_backend_int.h kind of useless, hence removed it.
