Remove pthread storage for thread local data

The thread specific QThreadData is currently referenced as a thread_local
variable and using a thread specific value via pthread_setspecific.

Having both is not necessary, as the pthread value is never directly accessed
and only used in the pthread destructor. Using a holder, we can achieve the same
and get rid of the pthread handling altogether.

This also fixes a bug, where the thread_local currentThreadData is already null,
when entering the pthread destructor. In this case it would lead to a new QThreadData
being created, when finishing an adopted thread.

Pick-to: 5.15
