Revert "Do not wait in QWindowsPipe{Reader|Writer}::stop()"

This reverts commit c7ec07d40115bef849574c81d619b629af9434a9.

Reason for revert: This causes a memory leak on program termination.

The initial commit was an attempt to fix a deadlock where the user
destroys object from a thread that does not own the object. This is
an unsupported case and should be treated as an invalid report.

Pick-to: 5.15
